it all depends on what state you live in. look that shit up man and also make your area distant from everyone eles in the house put a lock on it, that only you have a key too. she knows nothing, tell her no mater what they tell her (when and if the shit hits the fan) to not to say she knew about it, they'r going to try to get her to say that she new something, if you care about your fam, tell them to save themselfves no. one, you should have kept them in the dark, no 2. the only way for them to save themself is to play ignorant and plead the 5 (say nothing) " i dont know what my husband does up there thats his office/mancave",or "daddy doesn't allow us to even come close to his office, if he's there or not,if we want him, we must call him on his phone first then he alwas come down "
and also get those guns (any and all weapons, even display & replacas) legal or not out of the house
and even after all of this there no tellin, they may still take the house, and send the wife to jail, and put the kids in temp. foster care
