If you had proper training, you would know how to take down a guy with a knife while limiting your risk of injury.
This is a pretty dumb post. No matter your training it is not easy to take anyone down. Especially when they're in fight mode. Add in a weapon that can kill you in a split second and you need to be near perfect in a very imperfect situation to come out of it unharmed. There have been hundreds of cops killed in the line of duty that have had the chance to shoot a violent criminal but instead attempted to disarm them or arrest them and failed. Cops actually watch training videos of officers killed in the line of duty and how in just a split second you can lose your life.
If Im a cop and I have a wife and kids at home im not risking my life for some left wing hero criminal that abuses women and has a violent past. Im not saying yeah lets throw down with this violent criminal. The idiocy of the left, the media and celebrities here is just ridiculous. They're defending violent criminals and distracting from real issues that our inner cities face. All to stir up race relations before an election again.
