I don't know if it is the writers or CBS pushing it, but I've noticed numerous times while watching this show that they do a lot to subtly bash 2A causes. For instance, in a recent episode a bad guy is on the run and he walks into a (very stereotypically seedy) gun store and the loser-looking proprietor smiles and says "How can I help you exercise your second amendment rights today?". The bad guy then ends up stealing everything he needs to go on a full-out assault on the police, including multiple full-auto weapons and full body armor suit (including helmet) which he uses to mow down countless police officers and innocent civilians. The message is blatant: Gun stores are bad because anybody can end up with everything they need to militarize themselves and go on a rampage. It's almost as if Heather M. wrote the script for them.
I like the show overall, but I really hate it when they do things like that.
