Knife kicked out of hand.
When one of these young men starts reaching into a bag, the other does not recognise the danger he is in, and does not react accordingly. Police pay special attention to this kind of behaviour because they may be reaching for a weapon.
Police in this video clear a house room by room with a mix of best practice and sloppier methods (in particular brazenly opening doors and sticking their head or guns in) before they are confronted with a man who attacks with a knife. Luckily, in the last room they did not approach the closet door immediately and open it, allowing enough of a reactionary gap to avoid being stabbed.
A man with two knives attempts to stab a police officer. Due to sheer luck, he did not attempt to stab the officer anywhere except the stab-proof vest he was wearing.
A taser was deployed very little practical effect.
A fairly inept man drops his knife and is controlled effectively when this woman pulls his hoodie over his head. This gives her handles to control his posture, obstructs his vision and limits the mobility of his arms at the same time.
Suspect attempts to flee when a police officer searches him. As the struggle begins, a large knife can be seen tucked in to the rear of his belt. The knife falls to the ground as he escapes the grip of the cop. As the cop again grabs the suspect and pulls him to the ground, a bystander who apparently has some training in grappling assists by controlling the legs of the suspect. The bystander then transitions to a rear naked choke which effectively restrains the suspect who stops resisting.
Knife is taken from offender successfully with no apparent injuries (possible injury to offender’s hands) – a rare incident.
Police officer uses kick to knock over man who is holding woman a woman hostage with a knife to her throat. Others then move in to secure the man.
Complacent police surround man and fail to maintain a safe distance or keep their weapons ready. The man is able to close the distance and stab multiple police, possibly killing one before he is finally shot.
