Simply by allowing them in your door, anything they see can be used in order to obtain a warrant in regards to the cannabis issues and as they are investigating the accountant or whatever, give them absolutely nothing to be used against you and the most effective way to do so is to meet them in a neutral location. Now if it were the cops, I would just communicate with them by yelling through the window. I won't even open the door for them. Maintaining your privacy is not a grounds for obtaining a warrant and so long as your intelligent in other matters such as not leaving incriminating evidence in your trash and such, then you make their jobs very difficult. Especially when after you've made them go out of their way for months to find something relating you to cannabis, they come in with a warrant to find that you're doing everything in accordance with the law. Ahhh... F*ck you copsNo federal warrant no search and all objects siezed are done only federally sanctioned as well as they are not investigating you they are investigating the lawyer. He has absolutely no business in your room. Do not let him in there even if it's harvested.
