>> In what scenario could Brown injure Wilson’s face, and be shot by Wilson without gunpowder on the wounds?
big boy Brown punches Wilson so hard that Wilson staggers back.
Brown himself takes a step back to assess the situation.
Now they’re 3 to 4 feet apart.
Wilson shoots Brown.
Recall that the so-called "independent" Baden autopsy -- the only one that has been released to the public, so far as I know -- was conducted without access to Brown's clothing.
No evidence of gunpowder was found on the body...but wouldn't the clothing be more likely to harbor such evidence?
