Law enforcement officers who like gun control should be made aware of this story.
Ask a bunch of Ironworkers or accountants if they would like a law saying that Ironworkers or accountants could keep and bear arms but no one else could, and some substantial part of the group will say that looks like a good idea, and they'll even come up with reasons why it's such a good idea, that are specific to their group. The same dynamic applies to police. Many are patriots who support the 2nd Amendment, but some are not, even being willing to stand up with Clinton or Obama and demand civilian disarmament.
Those whose head is not too far up their rear end might change their mind though when they see the true face of gun control, which will ultimately disarm them too, unless they directly serve the government master instead of the people.
