Guns Don't Kill People, Guns With Bullets Kill People

Never bring an unloaded gun to a gunfight (h/t Instapundit):

A robbery and crime spree aided by an unloaded gun came to a halt late Thursday when the gunman met more than his match: a gun with bullets.

Charles Parker Jr., 18, of Detroit was killed when a 53-year-old man pulled out a 9mm handgun and shot the teen, who was armed with an unloaded .22-caliber handgun.

Detroit police are calling it self-defense.

So what is the proper way for police to respond to a citizen who has exercised his right to self defense?

After the shooting, police questioned the 53-year-old man and released him, noting that he had a valid concealed weapons permit.

Then they gave him back his gun.

Exactly. This was just the latest (and last) effort in Mr. Parker's crime spree.
