In fact, wtz badly required in police department is not muscle power, but sensitivity & intelligence.
Itz only in movie where one police fight with dozen of rowdies single handedly, jumping, bumping and all.
As long as, police department is run as political and caste sponsored drama company, they will not hv either muscle power nor intelligence. At present we still feel the presence of police station b'coz of those 5 or 10 % cops who r really effective and the corruption of balance 90%.
