A while back, that was a big issue for the antis. They claimed that retired police and federal LEOs could not be trusted, were a primary source of guns for crime, and you know the whole song and dance.
Did you know there was also a demand to disarm all police and federal agents? The idea originated in England (where else?) and was that crooks only carried guns because they were afraid of armed police so if the police were disarmed, the crooks would get rid of their guns.
Of course, the theory went, there would be some guns available for use only by federal agents under the direct control of the president, and the president would personally have to authorize issuing them.
Doesn't that sound good and give you a real warm fuzzy feeling?
