Can’t imagine any risk to 2 cops walking up to him on either side and disarming him.
If they can’t move fast enough to grab the knife hand, they need to get a desk job.
Well this man still had two arms and legs, police killed a man not too long ago who only had one arm and one leg, was in a nursing home in a wheelchair and “hemmed the police officer in a corner while waving something in his hand”, the item in his one remaining hand was a ball point pen. Compared to the guy in the wheel chair, a 95 year old vet with four limbs probably looked like King Kong on a rampage.
I have an eleven year old grandneice I would recommend to handle such problems in the future. I believe she could have handled this situation without having to kill one of our last remaining heroes from WWII and I guarantee she would not have gotten a scratch. In a worst case scenario she could have had her twelve year old brother help her overpower the dangerous individual.
