Jp1, great post
gimme, if you are still reading go to this page
http://www.odmp.org/search/year/2014?ref=sidebar
it lists the officer deaths in the line of duty in 2014 and read the stories. Then read previous years stories. Most of us do not go to work everyday and risk being killed. No matter how much it sucks to be a waiter the risk of being killed or even assaulted is very low. And if you were in danger you would call 911 for police assistance, wouldn't you? And police would show up to help you, and put themselves in danger to help you.
Many K9 deaths are listed too
The Ferguson story is very sad indeed as in any loss of life.
