Was wondering around wikipedia when i stumbled on the Civil False Claims Act, went a little further and found this...
http://en.wikipedia.org/wiki/List_of_Largest_Pharmaceutical_SettlementsThe charges include: Off-label Promotion, Kickbacks (political corruption), Medicare Fraud, Poor Manufacturing Practices, Failure to Disclose Safety Data, Concealing Study Findings (way too common), Illegal distribution, & Monopoly practices.
Gives you an idea on how corrupt things are over here on this side of the pond. Makes you wonder, how many times do you think everything went to plan and stood under the radar?
