IMO, you're confusing two separate issues. You're talking about behavior of the general public when encountering the authority versus behavior of authority figures. There is no formal training for how to conduct yourself when being confronted by cops. However, there was (I hope) formal training for the officer on how to handle situations involving suspects or people jaywalking. At issue is his decision to use deadly force. Based on what eyewitness have said, the kid was trying to escape. So what you will have now is people who like to believe that all black males are thugs painting MB as a thug who was attacking the cop...but no eyewitnesses support that account. So these folks will start going after the eye witnesses...especially the black ones.
