FDA Experts' Conflicts of Interest

As a governmental oversight agency, it should be appalling that the FDA uses experts who have financial interests in the drugs and products about which they provide expert testimony.  Yet, in a study conducted by the consumer group Public Citizen, that is exactly what is happening.  How can any expert provide unbiased testimony about a product in which they’ve bought stock or have some financial interest?  That’s not true oversight, but profiteering at the expense of the consumer.
