sanjay gupta. sanjay, first of all, what do you make of the latest numbers? years past, 3% in the last couple of years. is this a one-time spike or the beginning of a new trend. insurance companies when asked about this are saying the health care costs continue to rise, that's the problem. nothing has been done to control health care costs and they also say with the sluggish economy fewer people are buying health care insurance especially young healthy people, not as likely to buy health care insurance and that makes it difficult for insurance companies to rein in costs as well. there's one other point to this, wolf, when you talk about the affordable care act overall starting next year why f there's ever an increase of premiums over 10%, insurance companies have to justify that increase and some analysts say this is a proactive move. let's increase premiums now so we don't have to come increased scrutiny in the years to come. >> effectively these people are blaming president obama and the democrats' health care reform law for this dramatic spike this year? i

joining me now is sanjay gupta to sman what we heard today.ally comes down to this administering of propofol. i'm curious, is it actually lawful for any doctor to administer propofol in a private home in this manner? >> you know, it's interesting, piers, because the law's a little bit vague on this. it's so bizarre that i don't think anyone ever thought of it as a possibility, frankly. it is a drug that's used in hospitals, in icus and in operating rooms. and it's been a drug of abuse among certain health care personnel, again, in hospitals. but it's not a controlled substance. it wasn't at the time, still not. although people want to make it a controlled substance. so maybe not as much a legal issue as just an unethical, very poor judgment issue medically, piers. >> people are making a very big deal that he didn't when he got to the hospital tell people about the drugs that michael had taken. from a medical standpoint as a doctor, do you find that suspicious or do you think that someone who has just seen michael jackson die in his care has ju
