Nice to hear clear instructions from the get go...from the victims point of view obviously in a bit of a panic when faced with officers with guns and their usual demand of "let me.see your hands" he tried putting his hands up (I'm actually assuming the officers asked to see his hands too) - but as soon as he raised his hands they shot him? Then the same hing 30 seconds later? You can't ask to see someone's hands (asking in a very muffled way too) and then shoot them as soon as they raise their hands.
Another case of someone with the gun using force first instead of their brains - there are probably loads of different ways to have resolved this situation without killing the old woman.
Firstly they were warned by her family be careful with her) - why couldn't the officer ask her family to tell her to let go of the knives? Maybe the old lady couldn't speak english, or that faced with a gun a human looses all sense of calm and is rendered incapable of following simple instructions.
The training these "officers" go through must be absolutely shite, to go into situations with guns held high, no clear instructions etc will obviously create a very tense. and difficult situation, it's literally their job to contain and control those situations.
In most of these videos you see the officers panicking and absolutely shiting themselves in these instances, which means there's only a few ways these situations can go, sadly when it's dark and they throwing out different commands to their suspects/victims they're going to take any confusion as hostility and because they're so amped up and panicked, they shoot.
I was pulled over by police a few years ago (UK) just bought a car and it flagged up with no insurance, it was midnight in November (picked my girlfriend up from work - waitress, not a stripper) and there were 2 police cars and 2 riot vans and I'm a calm individual and never raise my voice (I'm a big dude, and get told I'm intimidating as it is) - anyway, I asked if I could start my car to keep my girlfriend warm, not ten seconds pass where another officer comes flying up to my window banging on my car shouting at me to turn my car off - the first officer literally didn't say a word, can't imagine what would have happened if they were armed.
