Deliberate ignorance of LEOs

I ran into a Central Florida police officer recently. It was a social situation, and we got to talking firearms. He made a statement to the effect that machine guns and 'silencers' were illegal. I explained the law to him and, since he was a supervisor, offered to come into the police station with some NFA items as well as the proper paperwork, so that his officers would know the law and be familiar with the proper documents that are required.

Hes response: "No thanks, keep that stuff out of my town." As if a person who has gone to the trouble of jumping through ATF hoops and is supportive enough of law enforcement to come in and train his officers is a threat to law and order.
