A few bad apples cause the whole cart to spoil.... this is the problem all cops eventually go to the "Blue Wall of Silence", hiding and abetting their fellow officers criminal actions, so as not to tip the apple cart altogether. From the turning a blind eye to spousal/domestic abuse (a large problem in the police departments), to the numerous SCPD's that have targeted women to strip/ or perform services to avoid DWI/DUI's (SCPD Officer Frank Wright, Mark Pav, Christopher McCoy, )... They even harass and attack their own, Sgt Cindy Olsen was assaulted by another SCPD on duty, the list goes on I recall having read in Newsday of 2 other assaults (one was a pregnant officer on desk duty - can't find it any longer, they do try to make these stories disappear and without names it is hard to find them years later to lookup).
Then you have the ones that have been made public, not the ones that they have covered up
