I pretty much agree with that. There's always the danger of someone relieving you of your gun, but generally, it's useless if locked in a drawer or a locker.
In the state of Washington, by state law you can’t carry in a court room, school, or bar. Any other place that has a sign and you get caught it is a matter of them asking you to leave. If you refuse to leave, then it gets treated as trespassing.
There was an odd letter written after the Sandy Hook massacre. It was in the form of a letter written to one of the dead teachers. Chastising her for not having a gun on her to protect her children. Went on about how “natural” or God-given rules are greater than some rule that man (the school) sets. It was too harsh in my opinion (the teacher was dead), but it does bring up the point that sometimes man’s rules are not just.
I always have a struggle picking my kids up from school. Bring the gun, or risk having my CCW revoked forever. So far I leave my gun at home.
