I just made up that analogy on the spot.
Latest news from Ferguson, MO is that Michael Brown had marijuana in his system at the time of death.
So my response is: Yeah, okay? If someone shot me in the coming week, my blood chemistry might show evidence of recent alcohol consumption. And?
Cannabis is not the type of substance that makes you behave in such a way that the people around you might fear for their lives. From what I hear about the effects of cannabis, it actually does just the opposite.
Renisha McBride had alcohol in her system at the time of her death. That explains how she wrecked her car, which explains why she was asking for help, but it does not explain why Ted Wafer decided to shoot her.
Michael Brown smoked weed at some point in the last 40 days before Darren Wilson shot him. That gives us nothing about the reasons why he had to die.
It reminds me of the range of reasons that many people have for labeling certain women and girls “sluts” after their rapes enter the news cycle. The word “slut” no longer says anything about their decision-making prior to victimization. They’re sluts because other people decided to do them harm. So it is with Michael Brown’s blood chemistry. He didn’t die because he was a cannabis user, he died because Officer Wilson shot him repeatedly.
