Delaware recently allowed hunting w/ .50 cal handguns.
In a fit of PSH or deliberate dishonesty, the article compared the .500 S&W Magnum cartridge, et al to the .50 BMG in range and power. Perhaps it was because they used the Joyce Foundation funded site ".50caliberterror" as their source of information. This was quoted and highlighted by the FSA's mouthpiece website the Gun Guys so I take that as that they support that little bit of disinformation.
The FSA's big gripe is "A .50-caliber handgun can easily puncture a police officer's vest."
So can most handgun cartridges over .38. But don't let facts get in the way of a good shorts staining rant.
Update: A response from the paper stated they're going to be publishing a 'clarification' w/i the next day or two. We'll see what they say.
