There is a saying that "christians are like windows, you only notice them when they are dirty". The situation is the same with Muslims. There are perverts, pedofiles, homosexuals, criminals, adulterers etc in any country. As Bornwithoutabrain said the police are understandably biased. Not only because the offender is a "Muslim","Arab" or a Qatar, but also due to the fact that there is the threat of loss of job if the offender happens to have connections in high places.
