This may seem nit picky, but it is like clips and magazines to me. I know I have erred in the past myself, but I am trying:
If a firearms company is selling to law enforcement they are selling to civilians unless said law enforcement is a military unit. An easy way to tell the difference is to ask the question "Can you quit your job anytime without going to jail?" If you can you are a civilian.
That doesn't change the issues of this thread, because I believe that our nation was founded with the intention that the power was to remain with the citizen as opposed to the elected official or special group.
