This is the training the police are not getting and until tactics change they will continue to garner bad press. You have to be trained in how to avoid confrontation, especially the fatal kind.
I’m not an officer, but I would have smoked that dude in the same scenario.
I’ve never faced a them with a knife, but Massad Ayoob and others have written that if a they brandishing a knife and advancing on you, as here, gets within 12 feet (the figure I recall) of you, then they’re too close and you should start shooting.
I know what you’re saying but when you think about it no logical person with adequate empathy should have to be trained to do this. It should come naturally. That said, I wish we’d have investigations into these training academies and have those in charge answer for it so the public can get a sense of just what exactly is going on and why.
