Strange the ways of justification . . .

I find it very strange that when people break rules or even a law, they find a way to transfer the blame without proving their innocence. My husband works in the public sector and they have a rule about the use of the computers in the building. People can call in and reserve a time and ONE hour and they can also have one, more hour if a computer is available. Two women have been finding a way around the rule in order to get on a computer and stay on it for two hours in a row. They call in their reservation, say for five in the evening. They come in at their reserved time, get on the computer and CANCEL their reservation BUT they are now on the computer and can have their FREE hour. Before they get started on whatever they are doing on the computer, they reschedule their reserved time for six o'clock thus they can use the same computer for two hours without leaving. My husband's boss talked to them about having to take their reserved time, get off and wait in line with everyone else to take advantage of another free hour. They were cheating, they knew they were cheating so what was their response to the person in charge? They called him a racist because he was enforcing the rules but was of another ethnic persuasion than them so they pulled the race card. Yes, there are times when prejudice can come into play but it seems so petty to use a serious issue to cheat on allotted time on a public facility's computers. I wonder how the culprits would have felt if THEY were the ones losing out on computer time because another person was pulling the same scam?
