I watched the entire videos of the man going after 2 woman with a weapon and not dropping the knife when ordered to do so by the police. This resulted in his death when he turned his attention to the police officers. Sadly the first person to start yelling at the police was one of the woman being attacked. Now the protests have started. I bet that if the police didn't intervene and someone was hurt or killed by this man the protests would be that Philly PD did not do their job. It's a no win situation for the cops.
