Police have said they found a knife in the car which could give just cause for the use of lethal force, although seven times to me is way too many. If you think you have to shoot someone seven times (and apparently only hit with four) at that range then I suggest you're not well trained enough in firearms to be entrusted with one.
Of course given the level of distrust in the police undoubtedly others will claim a knife was planted. Lack of bodycams is also a problem and will be used by some as a means of saying the police cannot be trusted.
I'm also unsure about the person filming it as he's said they saw the police Taser him, as well as punch him. but he seemed incredibly sprightly for someone who'd just been tasered.
Actions of some of the protestors to set fire to stuff and loot isn't helping anyone and harms the cause more than helps it.
The 17yo is despicable and he should have the book thrown at him.
Trump's over-the-top response is also going to do nothing but increase tension and you have to wonder if that's his aim after Mike Pence's speech about a Biden America being unsafe (even though his base will completely miss the point that this unsafe environment is under Trump's leadership)
