At least, they should allow the curious citizens to try out their NFA stuff on the police range. Maybe have a quarterly "shoot with the sheriff" or something. That would allow the private citizen to try out different NFA items before getting buried in paperwork and debt for a piece they may not really like when the new wears off.
Most likely in the administrative segregation unit, though; they should be in general population once convicted, IMO.
That could also promote a healthy relationship between LEO's and the subjects they rul... citizens they serve and protect.
Seriously, something like this would probably lead to less corrupt individuals in power, and more respect and cooperation from the public (because of the fewer corrupt LEO's). Not to mention the all weekend long BBQ fest I'm sure it would lead to.
If you want to keep all kinds of guns, you need to be a lic. dealer and don't sell a damn one.......Rat hole every thing out of ATF sight.... Your neighbor is your worse enemy....... Oh yea, keep a black marker as a high lighter like the U.S. gumbment does.......
