Lagopus,

The USA Constitution's 2nd Amendment states:

"A well regulated militia being necessary to the security of a free State, the right of the People to keep and bear arms shall not be infringed."

It is often debated here that this does not apply to individuals although that is the spirit in which it was written.

U.S. Code (of laws) forbids convicted felons and those found guilty of Domestic Violence (1st Class Misdemeanor) are not allowed to have firearms or ammunition. There are also laws concerning those with serious mental problems.

Interesting though in the US drunk driving is a misdemeanor but in Canada it is a felony. Plenty of American (US) hunters have been turned back at the Canadian border for having DUI decades past.
