YOU are the first responder. Police, fire and medical are SECOND responders.
When seconds count, the police are mere minutes away...
Gun registration is gun confiscation in slow motion.

My wife has had formal training and it helped.
Once she was not paying attention to the muzzle and I pointed it out--she immediately flashed on the husbands can't criticize reaction then remembered a second later how serious firearm safety is and said "you are right I'm sorry". I have to cherish the memory because it will not happen on any other subject.
