How do you know if MS 13 Are living in your area ?
If you are unsure ask your police department. Many times middle school "wannabes" attempt to tag everything in sight when they are bored. They may as well be peeing on fire hydrants...
ask people that you that may have it.
^ lol ............ Anyway if you did! you'd have gang tags every where of course it would say ms 13. And in roman numerals!!!!!!!!
They usually "tag" turf with grafitti.
there signature would be marked on certain areas around your neighborhood
