Right on! Hammers have killed more people than rifles, according to FBI reports. Handguns are far more often used than rifles. The AR15 is NOT an "assault rifle"; the definition of which is capability for automatic fire. The Sandy Hook shooter left the Bushmaster in his car, and used pistols in commiting his evil acts.These mass shooting have by far been commited in "gun free zones", including Aurora. Enforce existing laws. Only the law abiding will obey them; criminals will not.
