Very good job, Dottie! Meth labs are a serious hazmat health threat and if you share a building with one, you are definitely in harm's way.

The local police will not notify you of their planned intervention. It will as much a surprise for you as it will be for the offenders. I don't think that's necessarily a bad thing. Your being forwarned and gone for the raid might tip them off.
Take good care,
Okie
