A law is just a societal norm that sets a standard for behavior. It does not stop anybody from committing a crime who is predisposed to do evil or wrong. It defines what is correct behavior and then other laws provide punishment for "after the fact" for violating the norm.
Our problem is to find a solution to prevent any more of these tragic events. The politicians saying that new laws will prevent this is wishful thinking.
What we need to seek is a before the fact solution.
Have a nice day at the range
