DEA training: everyone shoots the dog

Radley Balko points out a passage from an article about DEA training for raids on drug labs:

The instructor knocks on the front door, shouting, "DEA! Police! We have a search warrant!"

The next thing you know you're inside, clearing rooms like a SWAT team on COPS, firing only at targets with odd numbers. The even-numbered targets could be the good guys, even children. Everyone shoots at the dog. It's covered with paint-ball splatters.

Balko quotes his basketball coach: "You play the way you practice."

And provides this link that proves it.
