One thing to consider is the amount of police officers behind bars,placed there do to minority speacial interest groups which have full backing of the judicial systems.  The lapd officers involved in the rodney king incident come immediately to mind.Wrongfull arrest,excessive force,brutality,shooting enquiries,almost 98% of these involve a ''minority''.  Being a cop behind bars would not be pleasent, let alone being sent there as a sacrifical pawn do to PC concerns by your own administrators.  Just something to consider.
