The media are discussing whether police should use or not use force when dealing with wrong doers. According to Wikipedia "the use of force doctrines can be employed by law enforcement officers and military personnel on guard duty and it can be defined as the amount of effort required by the police to compel compliance by an unwilling subject. However, a wrong doer is now dead as a result of use of force by police who put his knee across the neck of a hand cuffed wrong doer which led to his positional asphyxia and death.
It's not easy to talk about these kind of issues which have social implications but the police should remember that they are in the position of power when dealing with wrong doers and they should avoid unnecessary force which may lead to the death of the wrong doer>.
