KTC,
In a court of law you don't need a 'motive.'
I can't know what Officer Wilson was thinking.
That said, we know Michael Brown wasn't pointing a gun at him.
We know Officer Wilson's exchange had to do with MB getting out of the f*cking street.
The Officer was NOT attempting to bring MB in for questioning about the heist of cigars.
We also know the Ferguson Chief Jackson, did NOT inform Captain Johnson that he was going to release the video from the store.
We also know Chief Jackson was ASKED NOT to release it at the time he did by the DOJ, for fear it would add fuel to the fire.
We also know the Ferguson Prosecutor slammed Gov Nixon for putting Captain Johnson in charge.
IMO & in many others Ferguson Chief Jackson should be revealed from his position. He's proven to be inept, at best and a trouble maker at worst!
