A police record means you have made a crime or violation action before. So, does it affect on your chance of becoming a Police or the success of your interview? Yes, it does! So how do you fix it? how do you handle the question?

If you do not have any police record, the problem will become nothing; instead, it will only do good for you. But on the contrary, if you have one, don't try to hide it from the interviewer. Be straight about your mistake in the past and show that you are now aware of your action and have done many thing to improve yourself. Don't be too much worried about the fact that you have made a violation of law in the past; instead, emphasizing on your effort of improving to correct such an act.
