Govt' overreach.  Will not deter or keep criminals or lawbreakers.  Only deters honest people and puts more innocent people ar risk. 

Anyone supporting additional gun bans or limits that have or are protected by armed security or guards should be required for their armed security and guards to give up their weapons. Goes for the president all the way down to individuals. If you support gun bans or more gun control give yours up first as a test case and let's see how it goes.

Lead by example.
