Well a signed release or not, if this stuff was noted to be nasty, someone should be in trouble....I would never be involved in medical tests but one would think by the time they get to humans these medications are somewhat safer than this one appears to be...
But then again there are some people who think animal testing in wrong...
Why should someone be in trouble? Throughout history, researchers HAVE to use human beings in drug trials. If they didn't there would be no polio vaccine or any of the drugs that are used to successfully treat cancer. I think it's scary that this case is getting a lot of attention. Now researchers are put on the defensive - something that will possibly prevent future drug "cure-alls".
