you're gonna have to confront them or learn to deal with it. alot of times being confrontational earns you alot more respect than youd think. Dont be disrespectful but confront them about it, they know they are doing wrong call their asses out. atleast theyll have it in the backs of their minds that you know else its just gonna go on the same way getting the law involved will probably make it worse. be a shame if tey woke up one morning and all their car tires were flat after a game camera or stand came up missing....
