If 90% of the police were worse than terrorists, then India would be like one of our neighbours right now(read pakistan,bangladesh,sl). Police have a thankless job. Don't make judgements based on what you see in the movies.US has programs for their officers to visit psychiatrists when they get into high pressure situations. Notice how you to react to high pressure situations and imagine having to face that 24 by 7 for years together. You would be a mental mess too. Besides, you have to think like a rascal to catch a rascal.
Go home brother and enjoy a glass of wine and get some sound sleep. The police have your back.
