Media Bias and Self-defense

WFTV.com - News - Resident Shoots Masked Man In Alleged Self-Defense From the "alleged" in the headline, to the first sentence in this article we see bias in action.

CAPE CORAL, Fla. -- Law enforcement officials are investigating what they describe as a self-defense shooting at a residence near North Fort Myers High School.

Police "describe" this as self-defense. If they had arrested this guy, do you think this would be the phrase used? Or would they pile on?

It is alleged that he did not commit a crime. That is basically what the headline says. Does that mean he is guilty until proven innocent? Well, of course anyone who defends themselves with a firearm is guilty in the eyes of the media.
