Again, hard to make much of a judgement on this one. A few vague sentences. Nothing speaking to the crime they were chasing a suspect for. No mention of the suspect. No mention of how many police or if an officer was being bitten. Yet, we have a full page of people raging over police officers. I'm not taking a side, but damn guys, why do you get upset so fast over such little information?
Personally, if a cop breaks into someone's yard chasing someone completely unrelated to the crime, I don't care if the dog was biting them. That is a dog's job and maybe the cops should assess the situation before busting down someone's gate.
That being said. Cops have tasers, why not use that? Cops also carry pepper spray, which is effective on bears, so I assume it would work on a domesticated dog as well. It just shows that the first thing many cops think about is pulling the trigger. Or better yet, why didn't they just GTFO of the yard?
Edit: To clarify, if the police officer's life is actually in danger, fine. But "being charged" or even having your leg beaten, doesn't raise it to that level for me when you are in a completely innocent person's yard. Use your night stick, your pepper spray, or your taser.
