we start with breaking news in the trayvon martin shooting investigation. we're getting new details tonight about the moments right after neighborhood watch captain george zimmerman shot and killed the teenager. >> we can now show you the surveillance video of when he arrived at the police department that night. it was obtained by abc news, and it's from inside what looks like a parking garage at the sanford police department. in the video you can see the

police escorting zimmerman out of the cruiser and into the precinct. he is in cuffs the entire time. we're also learning that an initial police report lists the shooting as quote, homicide- negligence and manslaughter- unnecessary killing to prevent landfall acts, end of quote, but zimmerman was never arrested after a state attorney said there wasn't enough evidence. trayvon martin's mom responded on cnn. >> i believe that george zimmerman hunted my son like an animal, tried to detain my son. my son tried to get away, and because he could not detain my son, an altercation ensued, and my son was shot and killed. >> the case is now in the hands of a special prosecutor. investigators are reinterviewing witnesses and examining 911 calls, and all that investigating could take weeks to resolve. here in d.c. tonight politics 365 honored trayvon

with a game changer award. the group presents that honor to active people of color affecting change in their community. martin's parents got the award on trayvon's behalf at the ceremony on capitol hill. caught in the, a police say a former tsa agent was busted for allegedly running a prostitution ring out of a silver spring hotel. ken molestina is live with the details. >> reporter: that former tsa agent and now suspect is 39- year-old brian livingston of manassas. according to montgomery county police he was rang prostitution ring out of this hotel here insilver spring, the crowne plaza hotel. earlier we went by his home in manassas to try and speak to him about the allegations. >> yeah, he's up there, but i think he's a little upset that you guys are here. >> reporter: brian livingston's roommate was the only person who came to the door when we went looking for the man

suspected of running a prostitution ring. his neighbors say the allegations don't match his character. >> for two years i live here. we never had any misunderstanding or anything like that. he's a good neighbor to us. >> reporter: however, police are painting a much different picture of the suspect. according to montgomery county investigators officers were called out to the hotel on february 15th after reports that prostitution was taking place in one of the rooms. when police officers went up to the room they say they found livingston and 11 other people inside. the group included naked men and women. police say one of the men admitted he paid livingston $10 0 to enter the room and engage in sexual activity. >> i'm surprised, i'm shocked. >> livingston was arrested on march 16th and is out on bond living in his manassas home. a spokesperson says he is no longer employed by the agency. he had worked as a transportation security manager overseeing screening agents at dulles international airport. >> he seems like a pretty nice guy so i was shocked when i

heard. >> reporter: livingston is now facing five separate counts of prostitution. the tsa says he was employed by them for more than a decade. ken molestina, 9news now. the stakes couldn't be higher. i don't think there's ever been a suit where over half the states had sued the federal government over the constitutionality. >> but there is such a suit right now. and paul clement carried the ball for the opponents in the supreme court argument over whether the health reform act is constitutional. today was day three as the court focused on two questions. can the rest of the law survive if the court kills the requirement that everyone buy insurance and does the law go too fire in ordering states what to do with their medicaid program? gary nurenberg is here to report that whatever the answers are your healthcare costs will be affected. >> reporter: after tuesday's blistering questions about the individual mandate to buy insurance -- >> the individual mandate looks

doomed to me. >> reporter: the court wednesday heard arguments about whether the rest of the law can stay on the books if the individual mandate is found unconstitutional. >> my approach would say if you take the heart out of this statute, the statute is gone. >> reporter: the administration concedes provisions like requiring insurance companies to provide coverage for those with preexisting conditions and banning companies from setting rates based on a patient's medical history are dependent on the mandate. but argue much of the law sin dependent and should stand. opponents want it all gone. >> why shouldn't we say, it's a choice between a wrecking operation, which is what you are requesting, or a salvage job, and the more conservative approach would be salvage rather than throwing out everything. >> reporter: but just keeping parts of the law could potentially cost insurance companies billions, argued justice kennedy. >> that it seems to me, can be argued to be a more extreme exercise of judicial power than

striking the whole. >> reporter: but opponents will settle for amputation if they can't get depth. >> even if the court did nothing more than strike down the individual mandate would be a very significant victory. >> reporter: and "if" is the key. lawyers for states argue the law is unconstitutional. whether that law stands in fails we should find out, anita, in about three months. >> you're right, gary. while virginia and maryland are geographical neighbors it is mard to imagine two states whose attorneys general are more diametrically opposed when it comes to this law. i was joined by each to get their take on the future of healthcare in their states. >> gentlemen, thank you both for being here together. mr. cuccinelli, you have thread

charges to bring this down, and mr. gansler you have joined other attorneys general in writing a brief in favor of it. how do you guys feel after three days? >> this is just over two years old since at the present time signed the bill and it became law, and we filed suit the same day in virginia, and for those two whole years i had the same impression of our prospects, and that was that i was cautiously optimistic we would prevail. but after tuesday and the oral arguments i am more optimistic. i never want to get too optimistic because this is a case of first impressions. it means there's a wide open field. it's never been decided what. we're trying to do is take the whole what you out, not just some piece of it, though the most important thing 10 years from now is that that mandate be found to be outside the power of the federal government. that's a real threat to liberty. >> mr. gansler, your thoughts. >> i think clearly if you have any intellectual honesty about this issue it would be a 9-0

decision. obviously the federal government is allowed to, under the commerce clause, have people buy health insurance. they make you pay your social security, they make you pay your income taxes. >> none turned commerce clause. >> truckdrivers have insurance. they can send your kids off to war. >> not turned commerce clause. >> there's a policy issue, whether you like the policy or not, 99.9% of meshes have never read a word about it, but there's a lot of rhetoric. >> moving forward i know in maryland i spoke with montgomery county's health far. lot of changes have already started rolling, and in virginia as well. what happens if it is struck down? >> i don't think there's really a likely possibility that it will be struck down but if that were to help maryland, i'm on the committee that's going forward with that is work on putting exchanges in place, getting some positive attributes of the healthcare plan, the affordable care plan

in place. we're going forward with the good parts of the bill. that well, in virginia we're delaying implementation of some parts to see the outcome of the case. other parts, governor mcdonald ran on one element of his platform, creating state exchanges. of course, what the federal government hain mind and what he had in mind are rather dramatically different. they also, i would note, laid out a timetable that was virtually impossible to meet. interestingly the federal government hasn't met their own time table all of the various aspect of the rollout. i have no problem with that. i don't want them to hurry along and do more, particularly before the end of job before we really know what is the grounds that we're all operating from. >> mr. gansler you are confident it will stand, and mr. cuccinelli, you are confident it won't? >> i'm more honest here. he's spinning. i am cautiously optimistic that the mandate will be struck down. i think it is still, while i

drew a lot of comfort from the argument on severance i think that is still unpredictable and you could see the most movement between now and the end of june among justices. >> gentlemen, thank you. >> thank you. >> karen tolls is not going down without a fight. the prince george's county council woman accused of driving faster than 100 34eur7 on the beltway apparently is going fight that reckless driving ticket. police stopped tolls last month and officers say she hit speeds of over 100 miles per hour while driving her county-owned car. at first she was only cited for an unsafe lane change but then police reviewed the case and cited reckless driving. her trial begins april 20th. to cross a busy intersection in this area it's no sunday stroll. you're putting your life in your hands, or make that your feet. one out of every four traffic des in this area is not a driver or passenger, it is pedestrian or a cyclist. so local police have just launched a new crackdown on

both drivers and pedestrians like this one at silver hill road in district heights, maryland. >> drivers need to be cautious and ready at all times, and pedestrians need to walk as if their life depends on it, because it does. >> this crackdown is called street smart. it times reduce traffic fatalities through education and enforcement. in six days voters in d.c. will have their stay in republican race for the 2012 nomination president tonight one of the hopefuls hit the campaign trail. newt gingrich spoke to students at georgetown university. the former house speaker talked about his big ideas on everything from energy to social security and warned students that the problems of today will be their problems of tomorrow. >> this is your generation's greatest problem. you are inheriting from your parents and your grandparents a bureaucratic mess which is

stunningly incompetent following policies that don't work based on fact that are no longer true. >> okay. tonight was gingrich's first public event since he let go one-third of his campaign. >> he vows he will stay in race until mitt romney clinches the nomination. another republican candidate ron paul was in the area. he spoke to a packed house at the university of maryland. topper. the breedses are picking up. the cold front is about to move through. we hit 72 today. behind it, it will be cooler. here's your wake-up weather. light jacket probably a good idea. upper 40s, low 50s at 7:00. in the 50s by 9:00. we'll come back, tell you how warm it's going to get. we made some changes. if you know the theme song to the beverly hill billies, then you know the work of bluegrass banjo legend earl scruggs. he died today at a hospital in nashville.

he worked with other legends like bill monroe and lester flats and is credited from elevating the banjo from the rhythm section to a bona fide lead.

this video set to music has been playing around the museum for the past six nights. so what's the deal? we sent our own matt jablow out there to get it for us. he joins us live from the mall where it is playing right now. matt. >> reporter: derek, what do you get when you combine a classic american love song, some terrific vid okay grief, and one -- vid dee okay grief -- videography? this is it. there's a new exhibit at the hirschhorn sculpture garden. >> fascinating. >> reporter: actually, the museum is the exhibited. at least a big round part of it. >> many of the images move and float around the building.

>> reporter: it's called song one by multimedia artist doug aiken who married a wide variety of images to various versions of the classic ballad stilt only have eyes four." ♪ i only have eyes for you >> can't get enough of the song. >> reporter: he combined it all into a 35-minute presentation that's continuously projected by 11 high-definition projectors all around the outside of the museum from sunset to midnight seven days a week. >> what it's really about is turning the museum into liquid architecture. >> reporter: carrie broward is one of the exhibit's biggest fans and the curator. >> it's really an mating our national mall at nighttime. >> reporter: as you can imagine, the exhibit, which the museum calls the first of its kind in washington, is gadget lot of looks and a lot of

comments. >> very roman toys, and it draws you in. it's a wonderful use of the building in a different way of presenting art. >> reporter: the exhibit runs until may 13th, and i'm told there will not be a song 2, so get down here while you can. >> liquid architecture. i like. that. okay, parents, you may want to cover your kids' ears, if they're still awake. new research says school homework offers no real benefit until kids hit their junior year of high school. the study is from sidney university in australia. the data shows achievement rates are lower where kids spend more time in homework. that's because kids are unhappy about how much homework they're assigned. >> we knew. that you know you have arrived when new york's carnegie deli names a new sandwich out of you. so mr. tim tebow, congratulations, you have arrived. and here is your sandwich.

it's called the jet-bow. enough pastrami and roast beef to choke the incredible hull account. white bread, mayo, four full pounds of grub, surely enough to share with your offensive linemen, and with that white bread, i'm sure it will work wonders on your intestine. >> that's enough for a whole table. >> indeed. >> let's get to george washington because he has arrived. in fact, mr. president, sir, you've already got a rye whiskey named after you. in your honor master distillers from scotland have whipped up a special batch of would they call single malt near mount vernon. after all, sir, you produced thousands of gallons in your own day. this will be auctioned off for charity. >> not a single malt fan? >> no, i do not like single malt. i had a friend, he goes, it took me 35 years, and i like it

now. i'm like, i don't want to like it that bad. >> that's called developing a taste. >> that's a lot of work. 72 today have after our 55 yesterday, kind of nice. we'll correct a little bit tomorrow. cold front knocks the temperatures down, but still, seasonable levels. a live look outside. this is brought to you by michael & son. very mild out, 64. winds are still south-southwest at 6. so actually the frontal system has not moved through just yet. when the winds turn northwesterly that's when we know the front rolls through. when it's 54, it's not going to be a very cold night. satellite/radar combined, there go the showers and storms. the front will go through shortly. and really looking at a very thighs thursday and friday. so breezy and cooler on thursday, but still season afternoon. grab a jacket and certainly grab the sunglasses. pretty bright tomorrow. colder on thursday night, no frost or freerksz but we'll dip into the 30s in the burbs. still very nice on friday.

the week yerngsd we'll talk about that in a minute. maybe not so nice. overnight look for clear to part cloudy skies, breezy and mild, a 0 to 1 blanket night. maybe just a shee. even though the cold front comes through overnight the cool air doesn't move in tonight. in fact, it won't get in until tomorrow and tomorrow night. mostly sunny in the morning, breezy and mild. light jacket a good idea. temperatures 50 to around sick. but we have this northwest wind 10 to 20. that will make it feel cooler. by afternoon mostly sunny, breezy and cooler but seasonable, a very nice day. highs between 60 and 65. winds out of northwest 10 to 15 which is about arching terms of temperatures. everybody should hit 60 on this map, 61 gaithersburg, 63 in arlington, 63 in college park, 62 in bowie. out to the west, low 60s in reston and fairfax, but barrel 60 in leesburg around manassas but i do think they will make it. let's break it down to start 48

to 52 mild. by noon sunshine, 57 to 62. that's a perfectly good nan temperature for this time of year. breezy. by evening 59 to 64, cooler but season afternoon. the next three days very nice on friday, temperatures low sick. a few clouds will come in late friday. that's kind of a harbinger of our saturday. showers and thunderstorms, temperatures still in the low to mid-60s. the good news is we will still salvage a nice sunday. next seven days. sunday is going to be spectacular, mid-70s. 80 on monday. showers and storms possible on tuesday, upper six. there are still some indications that the middle part of next week we go back in the 50s for highs and maybe even another shot of cold air the week after. >> time to let that go. >> i know. but it's still march and the average last frost isn't until april 24th. speaking of april 24th, we could give up ton cast now and just look forward to the draft

on april 26th. >> where do you think is head is? >> still have a very slim chance. don't give up yet. the caps have just a few games left to make up some ground but is frustration getting the best of them in the locker room? plus find out why two elderly men got in a fate at a dialysis center. sports is next.

i said this many times in the past couple of weeks. the capitals need to pick up as many points as they can if they want to make the playoffs. after last night's blowout loss to buffalo the caps really need to win if they want to make the playoffs w. a handful of games left they control their own file. they basically need to win out to even after shot but this team is like dr. joke you will and mr. hide. they are anything but consistent. >> we've played very well against good teams and very poorly against bad teams. it's been a roller coaster. we have a chance to straint out

and win games. >> nicholas backstrom will join his team thursday on the road but he will not play. it's so that he can keep practicing with everybody. backstrom was cleared to practice five days ago buzz return from concussion is still day to kay. the nationals have just one week of spring games remaining and just one week to fill a few holes. it's looking like outfielder mike morris will start the season on the disabled list. it jayson werth starting to pick it up, solo homer. 3-2 victory. across the pacific in japan mariners and athletics opened up the regular season. huge game foimp radio. four hits including this rbi single in the 11st. mariners win 3-1. remember this broncos overtime win in the playoff, the touchdown from tebow? this was the first use of the new overtime rule. now it will be applied in the

regular season as well. no more sudden death o.t. decided by a coin flip. both teams will get a chance to score unless, of course, the first team scores a touchdown. finally tonight it appears march madness is making some people mad. at a dialysis center in kentucky authorities say a 68- year-old kentucky fan and 571- year-old louisville fan were arguing over who will win saturday's final four. one flipped the bird to the other causing the other to punch him in the face. >> i didn't talk to him about the ball game. i was talking to another guy. he told me shut up, and then give me the finger. i said, what? i'm not talking to you. i wasn't going to take no more of him. >> i'm sitting there hooked up to a machine. i can't do anything. >> i went over and hit him. didn't hit him hard, but i hit him. >> that's not march madness, that's march insanity. >> we'll be right back.

gee, kristen just bick said florida wasn't in the championship. >> don't remind me, derek. >> thanks for staying up with us. >> bye-bye, guys.
