Ferguson: too much or not enough?

[Esquilax]

Why isn't the question whether or not he did indeed commit the crime that was recorded?

Because the police officer that killed him wasn't aware that he was a robbery suspect when he pulled the trigger. It literally isn't germane to the situation at hand, and hence is just an attempt to paint Brown as a bad guy after the fact.

And how does this translate into the justification for looting, and escalating tension?

There is no justification for looting. However, the looting happened on Saturday, while the police were still shooting at and tear gassing peaceful protestors days later, which is the only point I made. It's strange that you missed it.
