Pity ain't got nothing to do with it

There's a wonderful line from the old parody book Bored of the Rings, where Dildo Baggins has failed to kill someone who otherwise deserved it.
When asked why, he said that pity had stayed his hand.
"It's a pity I've run out of bullets, he said."

Seems to apply to this situation as well:

But, of course, the ACLU is investigating this case of "excessive use of force", as is the FBI.

Pity.
