Dan_AZ...Unsure what you mean by "...weapon(s) able to fire lots of rounds." ALL weapons can do that. You must mean able to fire more than ONCE before reloading. And...."...rapid fire..."? HUH. Rapid fire would be a revolver...pull the trigger as fast as possible is 'rapid fire? Are you thinking he had automatic weapons? HE DID NOT! He did have the civilian AR-15, named the Bushmaster by the manufacturer. It is SEMI-Automatic. One trigger pull, one round. ALSO...NONE of Mrs. Lanza's weapons have ANYTHING to do with 'concealed carry. They were in her home. SHE is as culpable as he; she did NOTHING to rein in the years of bizarre and semi-violent behavior that SHOULD have been a 'red flag' to her that something was Terribly Wrong!
