Seven Mile Bloods tried "colonizing" my area...they messed up one house, tagged it...the house got boarded up and their graffiti got graffiti-ed over...but I haven't seen any new tagging since...most of our "gangs" are just groups of immigrant kids trying to espouse national pride. There's some graffiti over at Lonyo s. of Warren by the "Romo Mafia"...you just know that is some group of punk Romanian kids whose moms are waiting for them at home after they are done playing "mafiotzii." But I do have to agree that compared to some other cities...Detroit gangs are smaller and wield less influence over large territories..There is kind of an "everyone for themselves" mentality to a lot of the crime here.
