Even here in the U.K people forget what the Cops have to deal with, on a daily basis they risk their lives too, admittedly because of our Gun Laws etc it is mercifully rare that they face someone armed with a gun, though still a very real possibility.
But they have the absolute Scum, the Lower Sludge Pond life to deal with. And because our various Services have been underfunded for so many years, they have to deal with people with Mental Health and other problems that really should not come in their remit.
They are remarkably restrained when dealing with some A Holes, very Professional, and we are often given the wrong half of the story. I have seen many people at protests and demonstrations deliberately winding up the Police on Duty. No wonder they get a smack occasionally when things kick off !
Having said that, there are always within the Police bad elements who simply wish to use their power, and also may have racist or other bad attitudes, these guys are rare, but likely to cause a miscarriage of Justice, or even the death of someone. Bad Apples do not belong in the Force.
