How do we know if he was looking suspicious or not? If he wasn't looking suspicious then GZ would not have been calling the dispatcher about him. It was not just his race, as 1/3 of the residents were black, so it had to be more than that. And imo, the police reports do indicate there was a crime problem happening in the complex. It may have seemed 'nothing' in your estimation, but being home with your baby when two black males break into your home, in broad daylight, would be terrifying, imo.
