There are approximately 400 (plus or minus) people killed by law enforcement in the country every year. That's a little more than 1 per million. That number hasn't changed for quite a while. There is little question that the vast majority of those deaths are justified. If a (very liberal) 10% of the deaths were unjustified, that would mean that you have a 1/10,000,000 chance of being unjustly killed by a cop, and 99% of those are after committing a crime, in order for the contact to be initiated. A law enforcement officers chance of being killed in the line of duty is 1/4000 (per year).
Let's face it. People like to make things up to further their own agenda and others are dumb enough to fall for it.
The only thing worse than a liberal is a liberal that thinks they're a conservative.
