I think you mentioned Condo? Is there a condo association you can appeal to?
If its a rental, Landlord?
As for anyone getting deported, hey, its not YOUR fault they are here illegally, and the fact they know they are here illegally and wont turn down the stereo after being asked shows a height of stupidity. Im not Donald Trump, but to me sympathy goes out the window if an illegal doesn’t respect their neighbors.
Call INS, fuck them.
