Question about meth labs & stuff?

[Indy_Dem_Defender]

I have a neighbor I'm pretty sure is up to no good. I've notice the last few months the shrimp loser hasn't had a job, when he has worked it's usually part time being gone 15-20 hours a week. His mommie & daddie bought him and his girlfriend the house and I'm sure they at least use to pay their bills for them. Last few months I haven't seen mommie and daddie around, so I think he's been selling drugs to get by. Last night I had just came home and was outside when a cop car came down the street no lights on and shined his spotlight on their house and left. 15 minutes after this I here a bunch of noise outside, I look out the window and I see the loser throwing a bunch of stuff (couldn't see what it was in the dark) into the back of his truck and driving away real quick. I go out later on last night and see a cop van at the end of the street parked on the side street with no lights on it. So I know something's up with all of this, but I've heard a air compressioner running at different times from over at this house the last couple of weeks and I was wondering is an air compressioner is used for making meth or some other kind of drug?
