It's very possible that they don't need a warrant, if the landlord lets them in, and if your boy in fact broke his lease. I would operate under the assumption that they do not need your boy's permission to enter the premises. I don't know what to tell you about the rootballs though.
So my buddies girl contacted the property management company aka Landlord.... she said that the Narcotic Detectives are coming out tommarow..
If we toss all the pots and dirt...just leave the equipment are we still breaking the law? I mean do I have take all the equipment out tonight or once the pots/rootballs/dirt is all gone Im okay to recover the equipment later?
