I'm pretty sure you could get the homeowners association to kick them out if you could prove they were genuinely a bad thing for the neighborhood, but I'm pretty sure that stuff takes a long time to work out.

We had a similar situation where a rich Russian kid in our school tried to start stuff with a buddy of mine and him and his foreign friends were known to have guns and they even attacked one of my other friend's with a baseball bat (didn't actually attack, but htreatened) the whole thing kinda died down though, but it was funny because it all started with a drunken phone call. I think the guy eventually got arrested for gun charges because his girlfriend ratted him out cause she suddenly started hating him for some reason...

but anyway, I would probably just file a police report and call them next time anything even begins to happen, that way you and your friends will be blameless.
