that blue code is a blessing and a curse.  the awareness of and dedication to each other is good in that people will watch your back,  and bad in that those same people will "protect or shield" you from a valid review.  the number of cops that are coming from a military background, with the military mindset of kick a**/take no prisoners,  far outnumber the idealistic protect and serve cop recruits.  and as the protect and serve types work within the city seeing the worst it has to offer and listening to the constant rhetoric of fellow officers - they harden up - they have to.  i noticed years ago that when something "went down" and there was police action, the cops keep telling the "story"  to each other over and over.  i think it is a self preservation mechanism - should several cops get chosen for a review over the incident ...the " story" then gets retold consistently and unanimously.  probably not  intentional - but it is brainwashing just the same
