You need only look back to drug scandals like Vioxx to understand why the FDA doesn't want to have to respond to an angry public or face multi-million-dollar lawsuits if people start getting sick or dying due to an approved drug.
But despite safety concerns, many investors still put blinders on when it comes to certain drug companies.
