Depending on how bad the supposed traumatic brain injury was, maybe Mr. Scott shouldn't have been driving in the first place. Taking meds for tbi and smoking the ganga is a big no no. Or was the ganga to get his head right? Either way, he's gone and all of the protesting won't bring him back. You go to school, you get a job, get married have kids, stay married, don't do stupid shit, save your money, retire, pass away. What's so hard about that way of life? Stick to those rules and you shouldn't have to worry about getting shot by cops. From Mr. Scott's criminal record, it looks like he just couldnt get it right.
