Reluctant to go hands-on, police use their baton, then Taser which fails multiple times. One police officer attempts to knock over the man by rushing at him from behind but ultimately loses control as he stands up. The Taser is used again, then OC spray before the Taser is used once more before the man is taken into custody.
All of the tools police used in this instance depend on pain compliance, apart from the Taser which incapacitates for mere seconds IF the two prongs make contact correctly and in the correct positions on the body. Physical control with grappling techniques may have resulted in a faster and safer arrest, however these officers either lack those skills or were not willing to go hands-on.
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.
Police in the state of Victoria, Australia use pain compliance to handcuff a mentally ill pensioner.
The police officers used a baton and OC spray to achieve pain compliance as they were unable to handcuff the man by physically controlling him, perhaps due to lack of skill and/or malicious intent. Once he is handcuffed, a garden hose is used to decontaminate the man of OC spray, and this action has been interpreted by the public simply as further means to humiliate the man. An officer pulling out his personal phone to film the event only makes it look worse.
Police officer gives a mentally unstable Vietnam war veteran far too many chances, falls into verbal looping and fails to act until the gunfight starts. A prime example of why police shoot as soon as the threat of a gun is apparent, and also why they aim for centre mass. It is very difficult to shoot a moving target accurately under stress, especially when that target is shooting back.
Warning, the screams from this police officer as he is murdered are horrific.
