Scalia noted that the handgun is Americans' preferred weapon of
self-defense in part because "it can be pointed at a burglar with one
hand while the other hand dials the police."

Why on earth would I waste time calling the police if someone illegally entered my home?

My preferred weapon is still the shotgun. I am guranteed to hit the intruder and can easily dial the morgue with both hands free, for the intruder once I have emptied the shotgun.
