In a densely packed urban area a policemans handgun is a disaster waiting to happen.
Smart cops can almost always talk people into settling down. Dumb ones can usually tazer or club people into submission. Ultra-violent cops and jail guards sometimes beat people to death, but more often lives lost at the hands of police are due to reckless, instinctual handgun use. If a situation is so bad that the police really think they need deadly force a rifle or shotgun is a much better weapon anyways, and a scared cop is a lot less likely to make a tragic mistake.
Oakland is more dangerous today that it was a week ago. Especially for the cops. It should be. People have a not only a right but a responsibility to be outraged.
The sad thing is that those who are harmed by this are exclusively poor and minority populations in the city. What does this do to 911 response time when the cops are so scared they have to spend time warming up the armored car and rounding up the swat team before they will come to your address?
