Let's start with the idea that in your mind he committed robbery, which is a felony. Actually, the description of the event is much more of a shoplift, which is a petty offense. How is it that you get to decide it was a felony, by you looking at just one piece of evidence? I bet you or your son or someone else you loved has shoplifted once..... you thug! He never had a day in court to determine what really went on in the store. Fortunately, we have you to stand in judgement. Thank you for helping us shift through the complications.
You don't know, but you claim to know. These things are all true in your mind because you do stand in judgement, all knowing one. Modesty and humility are not your strong suit, as getting here requires many leaps of faith. Thank you God (who you must be since you seem to know exactly what happened), for posting to DP and straightening us all out.
That is one way to look at it. The other way to look at it is as complete Conservative BS where people disregard facts (we really don't know the facts, because they really haven't been presented) and just put things in boxes and those boxes labeled as good guys (angels) and bad guys (evil beings). In your world, people that are good are wholesome and people that are bad are pure evil and worthy of death. Sorry, but life really doesn't work that neatly. There is nuance in almost everything; there is good and evil at play in all of us. In this case, there seems to be more evil than anything; there are just a lot of bad actors involved.
From the Governor to the DA to the Chief of Ferguson Police to the leadership of the St Louis County Police to Officer Wilson to Michael Brown there is enough blame to go around for the killing, the investigation of the events, the "prosecution" and the crowd control. The whole thing is one huge tragedy of incompetence, including all the people that post here thinking this is just all about Brown being "a thug" and therefore his killing is just good riddance.
