There has been a little looking into the FDA regarding the Plan B 'morning after' pill decision. It appears there may have been some politics at work when the FDA rejected making the drug available over the counter.
The important parts of the story are not the specifics. (While interesting, they more give you a look into the workings of the FDA.) The important thing to note is that the FDA operates exactly as the NHTSA, FTC, FAA, Homeland Security, Department of Education, etc.
What does that mean? Well, that means that having the goverment involved in the regulation of things that do not fit under the Constitution, and having the goverment regulate things that are best left to individuals to decide, is always bad.
Even when you agree with it. Because someday, the government will use that power for something you don't like.
