I’ve been saying this for awhile, do the same antics to them that they do to others. Ferret them out and confront them, video tape the whole thing, upload the content and expose them. They don’t like it when they get exposed. They may not have jobs or a life that they care about, but make them uncomfortable as possible. Don’t let them slink back to mommy’s basement to hide out. They have low self control anyways and maybe you can get them on video attempting to assaulting you, then bamn, got them on a charge. Doesn’t matter if gets prosecuted or not, it’s on record and their name is in the system. Next time they get picked up, they’re a known entity in the police database.
