Aargh, your manager is silly. I've had managers like that, one turned out to be even dealing drugs himself while trying to give me a bad time when I spoke out about drug dealing in the complex.

Police usually ask that we call them and let them figure out if something is illegal. Can the meth guy really sue you for calling the police?

Any sort of dispute mediation service in your area?

So sorry you are going through this, I know from experience how much it sucks. Last thing we need, to be put in danger and then accused of being the problem, while the true problem isn't even dealt with.
