Pundit
The intention is punitive. The arrest is part of the intimidation. They use the occasion to beat him and subject him to all manner of indignities which they then blame of the accused man for resisting arrest. The police need reforms but not the type they are asking old policemen to carry out.
Until police education is raised to diploma above and above, you will continue to see all these problems. There is no excuse to recruit school dropouts just so that the poorly educated senior police officers do not feel threatened. I have suggested that in even a degree holder from certain disciplines presents himself for recruitment, he should be automatically taken - even if he fails on the physical test. It is not that important anyway considering Arachi can't score 25% in it if my frail grandfather tested him. Most officers become physically unfit immediately they leave training
I have also wondered why every police station is not staffed by a legal team comprising of lawyers or advocates. They do not have to appear in court but can help to process these cases, determine who should be arrested by providing a legal opinion to police commanders. This is how most civilized countries operate. By the time the police present cases to the State Counsel, all the holes have been plugged or by the time one is being arrested, there is sufficient grounds for it.
Sadly, politics and politicians still run the police.
