Paul Scott asks:"Unrelated but curious: Why won't you use your given name? Do you feel threatened?"

Threatened by whom? No, I don't feel threatened. 

Maybe it is more of a gutsy thing to use one's own name for some and denotes courage, but that is not necessarily the rule for everyone. In the past, I thought that using one's name was the courageous and honorable thing to do. Then, I noticed that responding posters were often responding more to the name of the original poster more than to what the content of the message is. Isn't it more objective and valuable to respond to the content of a message than to preconceived ideas about the poster who writes it up?

Putting aside the facts of what happened in this specific case, we have more police killings per capita than any other Western country (sorry, I don't have the reference). Have you seen the statistics on the subject- even from countries next door like Canada?
