It's distressing to see the elderly gentleman being peppersprayed. I believe I could hear him wheezing in the footage and saying that he couldn't breath. Despite wearing glasses, it seemed to go right in his eyes too, which he winced shut.
It seems obvious to me that the gentleman was immobile and I would argue that there was no imminent threat to life, which is the only time in which a taser should be used. I have great concerns about taser usage and the effect it can have on people, especially those with heart defects. A taser should be considered by police as a lethal weapon, only to be used in a limited number of circumstances.
My opinion is that taser usage is often treated as a punishment by police officers wanting to act as judge and jury. I've seen videos of officers in Lincoln aiming their taser at football fans in the street, seemingly to hurry them along. It's preposterous. The female in the video should not have fired the taser, especially when the male officer was already trying to retrieve the knife from the elderly man's hand. I don't believe that the policeman would have gone so close to the elderly man if he'd have genuinely believed there was a threat to his life or that serious harm would have been caused.
I am not defending the elderly man's actions, but I am criticising the police's actions.
I do wonder if the nursing home staff would have called the police had it been their own relative or if they'd have tried other methods of calming the situation - given the man's handicap.
