Not only did Vince and Linda grow up in Havelock, North Carolina, Vince was also a part of the gangs around there doing all kinds of stuff because he didn't have the personality to be "in" naturally like his brother Rod. Many of the gangs resented the military personnel, especially the black servicemen.

Anyone else just want to lock Vince in a cage and experiment on him? *looks at fellow BTVS fans to get the quote*
In all seriousness though, I'd love to peel back the layers of Vince's mind and just poke around trying to figure out what he's thinking and why. Such a deep background to explore
