captions paid for by abc, inc. good evening, i'm cynthia mcfadden. we begin tonight with the first public words from dr. conrad murray, the man who was with michael jackson the day he died and now according to his spokesperson has stopped practicing medicine while the investigation into the circumstances of michael jackson's death proceed. this case has raised serious questions about the relationship between celebrity and doctor. according to hollywood insiders, there are plenty of doctors willing to do whatever a star asks of them. even if it means forsaking their hippocratic oath. chris connelly gets the inside story. >> all of my patients and friends who have sent me e-mails, letters and messages to let me know of the support for me and my family. >> speaking out for the first time since the death of michael jackson, dr. conrad murray, who

was with jackson when he died, thanked his supports on youtube. >> because aftof all that is go on, i'm afraid to return phone calls or use my e-mail. therefore, i recorded this video to let all of you know that i have been receiving your messages. please don't worry as long i keep god in my heart and you in my life i will be fine. i have done all i could do. i told the truth. and i have faith the truth will prevail. >> dr. murray is at the center of the ongoing lapd investigation injackson's death and thought to be in part on the enabling doctors. who fed jackson's desires for pain killers. they're called doc hollywoods. they only find themselves and their patients in trouble.

he was getting a number of prescriptions under a number of different names. and this is a common thing amongst celebrity addicts because they demand what they want. and there are certain kinds of doctors who will give it to them because they want to be innary employ. >> in private practice and on "celebrity rehab", dr. drew pinsky works with the addicted. many of them well known. how often do you see these doc hollywood s coming into the lives of the celebrities who are looking for the powerful prescription drugs and enabling them in this dance? >> my job has become about taking patients, addicts, off of substances that my peers give them. this is just what i do all day long. and nowhere is that more egregious than with celebrities. if you don't have training in addiction, you can get into some serious situations. >> what motivated you to come and change? >> i just lost my life recently. >> i just was a -- was a little

miniature pharmacist. i just had such vast amounts. i was shocked sometimes that i lived through because i get it. >> women suit model and celebrity rehab veteran amber smith. >> this going to bring you up. this is going to keep me going. >> spent 16 years in the grip of an addiction to prescription drugs. >> i never ever admitted that i had a problem with drugs, ever. >> she was addicted by the time she was a teenager. her original symptoms were pelvic pain, headache and panic. once she found doctors to give her what she wanted she began believing she couldn't exist, she couldn't live without those medicines. >> i need opiates, because that gives me keeps -- that keeps me alive. >> she learned how to get the pills from the doc hollywoods. >> doctors get very starstruck. so it was like i was joining the club or rather they were joining my club.

i did kind of open up the purse by accident and they would see a "playboy" cover and say, is that you? oh, yes, i just got the headaches, i don't know what do. they were helping out a ha working model. >> absolutely no doubt that the doctors become seduced by the celebrity world and basking in the glow of celebrity and that's a boundary problem. you're not that person's friend, you're a doctor. >> did you know what you wanted? would you say, i need something to make me sleep or something to sedate me or would you say i need extra y or z drug? >> well, there's a fine line. i knew exactly what i wanted, but the thing is if you say, look, i need norco, over 325, tylo noll and i need 250, you can't -- you can't tell someone what to write. you can say i need something for pain and i need something very strong because i have had migraines a long time.

normally, narco works and i do travel a lot, so i don't want to keep getting refills. >> you're painting a picture of a very manipulative patient. >> i'm painting a picture of a drug addict. to me, the drugs are my life. if you take away my life, you're trying to kill me. >> it's brought deadly consequences to celebrities in the past. anna nicole smith's pled guilty for prescribing thousands of drugs to her before her fatal overdose in february of 2007. in 2002, a doctor had his license revoked for prescribing pain killers and sedatives to patients like winona ryder under the alias of emily thompson and to courtney love. michael jackson's search for powerful love even asked him --

led him to ask deepak chopra for drugs, and he turned him down flat. he knew other ways to get the substances that he wanted >> one way that the ctors are found is that they are concierge doctors in hotels. another way to find the doctors is through the rumor mill. you know, many celebrities are seeing the same people. so you know know who it is. >> am bier smith said she -- amber smith said she twice nearly suffered fatal overdoses, but the responsibility lies with her, not the doctorsho gave her drugs. >> a lot of people say to me, why aren't you angry? i'm in shell shock and i'm not used to people caring. ask me in a year and maybe i'll be a lot more angry for losing the best years of my life. >> 11 months clean, every bit a siren at 38, she is proud to be rebuilding her life. >> i feel like one wrong move and i'll be devastated. but i'm very hopeful.

>> tragically, it is too late for michael jackson, but in the wake of his life, drew pinsky says one-on-one doctor/celebrity relationships like conrad murray are too risky to be allowed. >> there should be ethical standards against being on a retainer, being a personal -- almost bodyguard physician. that's a situation that is just set up for trouble and there really should be standards set around that. >> and says deepak chopra, the doc hollywood culture needs to stop. >> the doctors are in denial of their codependence, frequently they're narcissistic. and they want to be important in the life of a patient. >> and very lucrative professional also from what you're sayin. >> it's lucrative professional. it is unethical, criminal. >> i'm chris connelly for "nightline" in los angeles. >> the los angeles police department sources tell abc news

that there are still weeks away from a conclusion of their investigation. thanks to chris connelly. when we come back, when the stars are cars, the paparazzi have to move fast. ñóñóñóñóñóñóñóñóñóñóñóñóñóñóñóñó new tide stain release. it's an advanced in-wash booster that works with your detergent to help remove the toughest stains the first time. new tide stain release.

it's back to school timeat staples over 7000 supplies at guaranteed low prices ♪ staples. that was easy.

day ♪ it's no secret the photographs that are worth the most to the paparazzi are the ones snapped when the celebrities least expect it. the furtive kiss, the bad hair day. but there's another sort of paparazzi out there, half photographer, half spy. their target isn't human at all. it's cars -- new cars to be precise. cars their manufacturers don't want you to see. at least not yet. tonight, neal karlinsky goes on the road with one of the leading car spies to see what it takes to snap hot wheels.

>> there's just something about a spy, especially one wielded by james bond that people love. >> using the aston martin -- >> but from slapstick spies from the old tv show "get smart" to "spy versus spy", you've never seen one quite like this. >> this is interesting. this is a car carrier and it gives it an indication that possibly more volkswagens are in town today. >> brenda pretty is a car spy. she does a lot of driving, driving the world's automotive companies nuts by chasing their newest models and prototypes and snapping pictures of them years before their creators want anyone to see. >> you know, i think they're trying to hide it from everybody. primarily their competitors. they don't want the competitors

to see what they have planned for the future. they want to keep it secret until the auto show somewhere. >> the cars are incognito, disguised with black coverings over key features. the glimpses will sell to magazines and websites in dozens of countries. an exclusive look at the new presidential limo. there's a reason they call it the beast. >> president obama's new limo, caught on camera by brenda's tome of -- brenda's paparazzi. >> i make the most out of everything i shoot. so, you know, if i shoot a $12,000 kia or, you know, a $70,000 luxury car, i get just as excited. >> she let us tag along on the prowl if we agreed to keep her exact location secret. and as long as we could put up with the two dogs who normally ride shotgun.

this patch of desert in the southwest is ground zero for every car company on the planet to test their newest ride, under intense triple digit heat to see how they perform. right now she's chasing what she believes to be a 2012 volkswagen suv hybrid that's never been seen. safe to say, the people inside are not happy. >> when they say no photos, that definitely means go for it. keep on shooting and shooting and usually people that are with me have to drag me away. >> here a german engineer from an earlier chase is trying unsuccessfully to convince her not to take any pictures. and she has a vast collection of shots like this of annoyed test drivers and specialists from around the world, blocking her, trying to scare her away by taking her picture and even mooning her. how annoyed are they with you?

>> they're very annoyed. they leave the proving grounds and are told, don't let anybody get photos. and before the day is done, you know, the photos are blished on the internet. so they get pretty annoyed with me. >> you love that? >> well, okay, maybe i do. >> she says all her shoots are perfectly legal. she stays on public property. it's not a concept familiar to some of the engineers who come from other countries. this one tried to run down her son. she ended up calling the company's headquarters. not for the first time, in order to settle things. >> when she closes in for the kill, get out of the way. it's like watching a predator. i mean, she's vicious. >> both her ex-husband and an exhighway patrol man who works for her says brenda is the master. >> she is so unassuming. you don't picture her as a spy photographer. she's the housewife, you know? but she's really good at it

though. >> while she's shooting for three months straight based out of a flea bag motel in the she knows the route. >> what are you guys going to do the rest of the day, just drive this up and down and hope nobody takes your picture? >> yeah. >> and their nemesis will be out there too. chasing them through the open roads of a vast desert. like all good spies, watching and waiting. i'm neal karlinsky for "nightline" somewhere in the mojave desert. >> our thanks to neil larkinsky. when we come back, matching words to video, literally. it's "a sign of the times".

ar st t here. go further. and back in the 1980's music vios added pictures to the sound track of the generation. but looking back it's often difficult to figure out just what some of those artists had in mind. the song and the picture don't seem to match, so now comes the spoofs. the lyrics replaced by a description of what you're actually seeing on the video.re the results are pretty darn funny and therein lies "a sign of the times". ♪ ♪ bright eyes >> looking back, the golden age of the music video was pretty silly. all that lip syncings, the characters, the images that had

nothing to do with the songs. really, what were they about? take for instance the red hot chili peppers "under the bridge". sometimes i feel like my only friend ♪ ♪ >> what would happen if the lyrics of the song described exactly what you see on screen? ♪ sometimes i'm shirtless and i tilt my head ♪ >> billy idol's "white wedding". ♪ ♪ you can smell my breath, he's a doctor who make the day ♪ >> a young guy in los angeles is digging up and rewriting the lyrics to old videos to accurately match lyrics to the picture. ♪ it's a good time for my cool glove ♪ >> dustin mclane calls it a literal video. >> it's seeing what's happening in the video and that ends up being really funny for some reason. especially the weird videos where strange stuff is happening. >> his knock off of aha's "take
