It took me several re-readings to conclude that "them" and "they" at the end of this sentence are referring to different people! I think what vkou is saying (and I agree) is that while there currently are some police in prison who have been convicted of crimes, the difficulty factor of convicting a police officer is much higher than the difficulty of convicting a normal person. If the same higher standard for obtaining a conviction was applied to everyone else, hardly anyone would be sent to prison.
