There are a LOT of formerly incarcertated people in the local slum areas I am GLAD have lost the right to own a firearm.
The constitution bans guns for felons, doesn’t it? (real question)
No. US Constitution.
Ban on arms possession by felons is a relatively new feature of US law, 1938 Federal Firearms Act, replaced by the 1968 Gun Control Act. See Law Review Article advocating felon-prohibition in Vermont State law, and Gun Control Timeline
I don't know. Does it? (real question)
And if it does, what acts qualified as "felonies" when it was written, as compared to what qualifies as a "felony" today?
