How do we know that this juvenile record is for the Michael Brown that died on the street in Furgison?
Michael is the 4th most common given name in the US, Brown is the 4th most common surname. Even with less common names, assuming that only one person has that name is a classic mistake.
My understanding, he has 2 middle names and is a Jr. Surely there is a SS#. I really don't think it will that hard to narrow it down. After all this, I'm sure the officer(s) that arrested him or charged him, could speak up and say, I remember that guy. It couldn't have been that long ago.
And what about mug shot???
