I worked in the ER of a large,"big city",hospital for years.It would take me a long time to explain to you just how foolish that statement is.
The key words in my post being “law abiding citizens”. For example, I have never even ever talked to a drug dealer in my life, let alone have a drug dealer point a gun at me, but like almost everyone else, I have had some interaction with the police. That is why the police need to exercise great caution. With great power comes great responsibility.
