Very interesting.
Here is one of the studies. Do a search on ‘police abuse of force’ and you’ll find a lot of info.
http://www.ncjrs.gov/pdffiles1/nij/181312.pdf
“more than two-thirds (67.4 percent) reported
that police officers who report incidents
of misconduct are likely to be
given a cold shoulder by fellow
officers, and a majority (52.4 percent)
agreed or strongly agreed that it is not
unusual for police officers to turn a
blind eye to other officers improper
conduct”
Another interesting factoid, 15% of excessive force claims are made against less than 1 percent of the officers.
