tonight, cara meets her avatar as we learn about the movie magic that could bring seymour hoffman back to life. >> lined say moran is an analyst. she is showing us the virtual reality that may bring peace to our traumatized war vets. i am phil torres, an entymologist. let's do some science. >> welcome to "techknow." you guys have some very fascinating stories today. rita, let's start with you. >> as a society, we have really started to value where our food comes from. we don't always think about what's happening in the process picked. i got the checkouts and innovations in agriculture that are taking robots out of the lab into the fields and it might mean in the not too distance future you are eating food picked not by a human hand but by a robot. let's check it out. >> do you eat strawberries a lot when you are here. >> i do and for breakfast. >> the terri family has been farming in ventura county, california since 1890. the world has changed dramatically since then. one hasn't. >> in 1969 we put a man on the moon but brought him back safely but we are harvesting a strawberry crop the

one could be jeff daniels, the other could be philip seymour hoffman but he's dead. >> he did pay a lot of attention in virginia, but in other congressional districts he tried to knock off the chairs in those districts. he got beaten. he wanted the whole of virginia to have a grassroots operation. he went after chairmen in somebody else's district. that's something you don't do but he was not paying attention to the people who vote in primaries. >> and his top lieutenants were defeated, so he was left with no real grassroots presence and a lot of people said to him let bygons be bygones. make peace with the grassroots party. he didn't do that. if he didn't go with the strategy of going to war, his opponent wouldn't have got the 35%. they thought they could take him down, they are going to win by 20, 30 points. >> other congressional districts came in and helped -- actually turned out -- >> they did. they worked very united to defeat him and a quick point about the democratic turnout. a lot of people say democratic turnout wasn't high. that is true in typically african-american districts

obviously if phillip seymour hoffman's death didn't occur we might not be talking about that. when the autopsy was performed on him he had schooled heroin, he had five other drugs in his system, yet those wert citeat all as contributing to his death. so why is heroin the only thing that killed him and not some of these other substances? i can't give you stasks off the top of my hea --statistics off the top of my head rite now, but it tends to, when horrific things happen that really are extremely sensational. >> going back to meth, rehabs.com put together a famous campaign, about ten years ago, mug shots of meth users, the horrible impact kit have on people in short periods of time. and the pictures really shaped what a lot of us thought would happen if they got looked on meth. very frightening but you say these types of campaigns don't work? >> i don't know about research about the face he of meth campaign specifically. i have read some research about the montana meth project which has similar predictions, and some studies show that hasn't had much effect on reducing meth use

because the drug business is consensual, for example, the actor philip seymour hoffman recently diedf an overdose, he died as result of a consensual drug transaction, as almost all drug transactions are. he and the other 13,000 heroin addicts who die each year are equally dead, whether it's consensual or whether there's been violence. we need to stomp out the harm that comes from the drug trade, a harm that is one of the most destructive, particularly minority committees that's going on in the united states today. >> would you mind if i added one thing? >> it's up to the chairman. >> with regard to everyone there's been since 1990, the purity has gone up 60%. the price has dropped 81%. so it does indicate what we're doing with regard to heroin is tragically not working, and i think obviously those, particularly kingpins didn't with heroin and other hard drugs should go to prison. but what we needed to go -- take a broader approach good for our pharmaceutical advances that are treating her with addiction and also recognize prescription drugs even with the increase in heroin abuse, it
