Chances are if he was white, Officer Slager's entire attitude towards him would be different as would his past experiences with cops.
You know, when a white guy gets shot by someone, no one sits and says 'he had a lot of parking tickets, and he probably shouldn't have been in that neighborhood at that time, and honestly once ten years ago he definitely got in a bar fight'. Because that shit is not related to what happened.
You're using 'she wore a red dress, of course she got raped' logic.
