our crews say it's busy down downtown but police tell us the everything is okay right now. police are ready to divert crowds. last year police ended up arresting 18 people. we go to john sasaki who has the ground perspective. >> reporter: drivers are still cruising the area showing off their mexican pride. cars and trucks have been cruising santa cruz police flying red, white and green mexican flag. police are out on cars, motorcycles even horse back. problems that seem unconcerning to residents. >> i live here in san jose, i believe our police department

does a pretty good job. i think they prepared very well this year. we haven't seen a problem. >> the reason i continue to come out every day is important to be able to separate the culture with the problem that happens on an inherent city. >> reporter: police are outlooking for drunk drives. >> you have 40alka sensor machines. >> they could invest in building the city up and to compete with santana row with free parking and with entizing people to want to come downtown again. >> reporter: plenty of people are coming downtown including these teenagers who showed their love of their heritage. >> i'm really proud of my country, just for that day. because when my grandparents tell me all the stories and

they were outnumbered but they still fought and they won. >> reporter: this is the look from news chopper 2. i just walked up there and there was traffic jammed up from both directions. you can see that some traffic is being diverted into that area. john sasaki, ktvu news. the person who committed san jose's 16th homicide of the year remains on the lose. demetrius campbell remains on the lose. at this hour police are not giving a description of the suspect. we have new information tonight about a possible terror plot targeting the rail system in the united states. the evidence was uncovered by

commandos during the raid of osama bin laden's home in pakistan. the idea was to detail a train perhaps on a bridge. it was to be carried out this september on the tenth anniversary of the 9/11 attacks. eric rasmus has the details. >> reporter: officials are telling police to keep an eye for pins missing from tracks. we have long stretches of tracks. sending people off the bridge could have been the next hew move from osama bin laden. it's part of a homeland

security intelligence warning just sent to law enforcement around the country. it's troubling news for some regular passengers at the amtrak station in martinez. >> it does concern me, yeah. i think they should up the security and i think they should be looking for suspicious packages, suspicious people. >> reporter: amtrak confirmed it received the tsa warning and told ktvu we are immediately privy to any intelligence with response to rail. the plot to attack trains may have been in the works for more than a year, but u.s. officials say there was no indication of an active plan in place. >> i just hope it doesn't happen. >> reporter: at this station, many told us they still feel safe and are hopeful the same mission that killed osama bin laden can also help fend all other attacks. >> it's good that they can stop things in action right now. >> reporter: now union pacific

wouldn't talk specifically about this new warning tonight. but one official did tell us they do work regularly to update their own security procedure. we're live here in martinez, eric rasmusen. president obama went to new york city today to pay tribute to those who died on september 11th. he laid a wreath at ground zero. >> is president then met with some of the families of 9/11. we will have full details on a live report from new york city. that's coming up in 15 minutes. we saw jason naso in court last month. he's charged of killing four women several years ago.

today the 74-year-old said he wanted to represent himself because he was the person who knew the case the best. and that attorneys were too expensive. -- fire chief joanne hayes white tells ktvu that there is no evidence that a bbq lit inside sparked the case. and we are told that a chihuahua found in the rubble has been reunited with its owner. construction workers punctured the plastic pipe at around 3:30 this afternoon. news chopper 2 was overhead as crews surveyed the damage. police closed bush street.

crews repaired the line this evening. pg & e rates are going up again. this time it's because of those controversial smart meters. ktvu's consumer editor tom vacar tells us why customers are now on the hook with old meters that are headed to the dump. >> reporter: pg & e customers will pay $2.2 million for the installation of millions of new meters. but consumers will continue to pay for the old analog meters that are now being removed and junked. >> it's approximately $110 million that customers will be charged. what that means is that consumers will basically be paying pg & e profits on meters that are destined for the trash heap. >> reporter: pg & e sees it

another way. >> the >> reporter: those pg & e meters are being replaced earlier than originally expected. the profits that pg & e expected are also gone. the cpu ruled today pg & e is entitled to that money. so now rate payers will have to make up that difference. >> what are customers getting for all this investment? we haven't seen yet any great savings in energy or money from the smart meters. >> reporter: the continuing smart meter controversy only adds to pg & e's pr woes. exacerbated by its failed prop 16 and of course its disaster in san bruno. tom vacar, ktvu news. and pg & e has tapped an outsider to look into the response of the san bruno

explosion. nick stavropoulos will take over. economists are offer various opinions tonight in the spikings of unemployment filings. the new filings hit an eight time high. lay offs coincides with spring break may be to blame. i'm back here in about ten minutes, it was warm today but temperatures are going to drop off in a few days. it wasn't just any strike here in oakland today. we'll tell you why the nurses and children's hospital contract battle could have a domino effect throughout the region. we showed you this

this video just came into the ktvu newsroom about 45 minutes ago, a witness tells us at about 8:30 tonight, the driver of a van made a u turn at the intersection at the intersection of davis street and crashed head on into a police cruiser. it's not clear if the officer was injured but he managed to arrest the driver of that van. nurses at children's hospital in oakland have law firmed a five day strike. they say they are fighting to preserve wages and health care

benefits. tonight-- nurses at children's hospital in oakland have launched a five day strike. and jana katsuyama is live with a look at what's at stake. >> reporter: it's a tough battle today. today the nurses took their picket line right up to this security fence that children's hospital put around the building. the main battle is over health care benefits and it could have an impact on nurses region wide. nurses waged picket signs and passing cars honked their horns. inside clinics and operation rooms are running at slightly lower capacity today. >> i understand that it's 40% or so of the nurses that were supposed to work today crossed and aren't working. >> reporter: the union represents 794 nurses at the hospital. what happens on this picket line could have a domino effect throughout the region. for decades the union says the bay area standards has been that bay area nurses do not pay monthly premiums for their

health care. >> so if we did that that could have an effect on all the other nurses. >> reporter: that includes all the other nurses. >> we're afraid that the same thing is going to happen to us that they are going to chop away our health benefits. >> reporter: the hospital is facing tough financial times and is asking nurses to pay a premium of $7,000 a year is not unfair. >> 7% of our patients are government funded. it's unfortunate the union would use this hospital where they are putting the stake and unwilling to look at any kind of contractual change. >> reporter: nurses say they plan to stay on the picket line till tuesday. an update tonight to a

story we first told you about back in february. six people are under arrest this evening accused of a home invasion in gilroy. news chopper 2 took photographs of the home. three men broke into the home and waited for the victim to come home. when they did they ambushed him and tortured him to get the combination of a safe. >> not only these suspects beat up the victim with cue sticks and wooden sticks, but they also poured a liquid chemical substance all over the victim's face and his body to create more pain. >> reporter: the safe contained a collection of gun, stamps and coins worth an estimated $200,000. the six suspects were arrested last night. one is a juvenile, another lives on the same street where that robbery occurred. six of the seven people

>> when we say we will never forget, we mean it. >> reporter: another symbol that america is moving forward, the site where the twin towers stood. president obama is set to meet with the navy seals. samantha hayes. members of the menlo park firefighters paid special attention to the president's visit to ground zero. >> it's not really closure, it just helps heal the wounds. >> reporter: some of the bay area firefighters say they are suffering chronic breathing problems from inhaling dust. they had to communicate with radios so using respirators in that environment wasn't always

possible. the firefighter says what they breathed in must have contained remains of the people trapped in the rubble. the firefighters say they would do it again. and ahead tonight, how especially train dogs can serve as vital tools during combat operations. that story is coming up at 10:45. a nuclear power plant just yards from the california earthquake

a major sign of progress in

japan. today crews began installing ventilation equipment at one of the reactor buildings that was damaged in japan. this is the first time workers have gone into unit one. equipment has to be ventilated before cooling equipment can be installed. crews can only spend a few minutes inside because of the high levels of radiation. uc berkeley experts tell ktvu, radio active isotopes from japan picked about three weeks ago here in the bay area. tests do show minuscule traces in some foods and vegetables here but they are well within safety units. uc radiation scientists says a person would have to eat 1,000 pounds of spinach to get the same amount of radiation as in a cross country flight. a nuclear reactor sits right on top of a newly discovered fault. the power plant is up for renewal and many people are

worried about a fukushima style disaster there. john fowler tells us why the approval process might be fast tracked without a seismic assessment. >> reporter: the village of avila beach, six hours drive south of san francisco. the this popular beach town lies on a seismically altered coast. some residents are now weary after the japan earthquake tsunami and nuclear disaster. >> for the diablo nuclear power plant that really does scare me. because we are so close. >> reporter: geologists pointed me to this promitory on the coast. they say this is clear evidence of what's called a vertical thrust fault. how recently it's been active? impossible to tell. >> some of the simplistic models may not be adequate to

see what is happening. >> reporter: sam blackesly is the unlikely leader of the not so fast movement of relicensing diablo plant. at a similar pool in japan, a tsunami turned off cooling systems in the radiation plant. >> what surprised me most is they weren't as prepared as they should have been. >> reporter: strickland points to specially engineered transporter and dry storage casts. this spent fuel storage is necessary because there's no long term disposal. despite billions of the rate

payer dollars sitting unusable in a fund. all this is designed to with stand a 7.0 quake. >> it's unlikely that we have an earthquake, it's unlikely. that's exactly what they said about japan. >> until you understand the threat you do not yet know the degree of safety. that's the other side of this equation that we need to get our hands around and do so quickly. after blackley threatened legislation to stop the process, the company sent a private letter to the nrc saying it still wants expedited safety review. >> if it's identified that the hazard is greater than what

we're designed for. then the nuclear regulatory will not allow us to operate. some people around here tell us despite the apparent corporate duplicity, plant worries are overblown. >> i've lived here all my life. all my life i've been told we're going to have a big one. i'm still here, we haven't had a big one. >> reporter: but seismologists say a quake here is coming, they want to know the risks in advance. john fowler, ktvu news. more news coverage from chopper 2 of the cinco de mayo celebration. you can see a lot of motorcycle police officers have gathered, it appears they pretty much dispersed the crowd. there were reports that they were taking rocks and bottles from some of the partyers and working to keep the crowd in check. now they just appear to be keeping an eye on things. if we get more information we
