The second ammendment doesn`t mention police not being able to bring thier weapon into jail iether but they drop them at the door for a good reason,
And how many officers lives would be saved if they were allowed to carry their duty weapons and simply shoot the criminals the instant their lives were threatened. Or if the criminals had their butts locked up like they should be instead of out playing basket ball and lifting weights.
Legislated helplessness.
But this is another topic all together.
most laws are there for a very good reason
I guess as long as enough polititians think that the next gun law is being made for a "good reason" or is a "common sense" law it will be ok and we should just accept it.
