In day-to-day police work, such expenses are commonplace and, regrettably, there is no easy system for reimbursement. An investigating officer is thus left to fend for himself. What does he do in the process? He makes up by becoming a part of a system of collusive collection of money from people who themselves are trying to misuse the system. For instance, if you are running a bar, if the scheduled time of closure is 11 pm, you may like to run it till midnight to make some extra money. You pay some to the excise department and police to look the other way while you run your place for an extra hour. It is a collusive system because both sides stand to gain. Most expenditure made by the police for legitimate jobs that cannot be recouped on account of cumbersome governmental processes is taken care of by such well-oiled collusive modes of money collection… I am not trying to justify corruption in the police but am only giving an insight. Of course, as and when a specific act of corruption is reported it is dealt with without demur.
