1 The mass shootings exclusively occur in "gun free zones".  Officials in many local jurisdictions are power anti-freedom and do not need the power to set them up.

2.  Guess what, we already prohibit people we deem not to be trusted with firearms.  What your side of the aisle is proposing is to expand that list to people who have not had due process.  That is objectionable.  There should be National CCW reciprocity specifically because states should honor CHL's like they do drivers licenses.  Also those states with may issue show how local governments abuse their power.

3. You haven't proposed anything specific so all I have to go on is the ridiculous proposals your side of the aisle has brought up and the stupid restrictions that need to be repealed.

4.  I did so in the first part of my comment that you responded to.  Had you done your research, you would see there have been gun confiscations in all 4 places.
