Normally, I am a states-rights libertarian (small l). I believe that Roe v. Wade was the ultimate in a century's worth of court cases trampling the powers of the states. However, I do believe that the Federal Government can be right when it bars the states from acting. The Federal courts were right to act against Jim Crow, since Jim Crow was the ultimate anti-libertarian expression. (Seperate but Equal isn't when the government acts as an agent to keep things unequal.)
Here, the State of Florida is making a civil death sentence that allows the level of heresay that wouldn't convict a person of littering, much less a capital crime. The Federal Government IMHO has the authority and obligation to prevent that kind of crime.
