They prolly won't be back, but ... I would find an atty that specializes in defending MMJ cases and spend a C Note and talk to him/her for a half hour.
They know the way the jurisdictions in their area act.
And you'll get much better advice than you will here.
But, IF you get popped ...
Identify yourself honestly.
Do what they tell you to do.
Explain that they do not have your permission to search, and never did ... even if they have a search warrant. Say it frequently in front of many witnesses.
Ask if you are under arrest ... if not, ask if you can leave.
Explain that you will not be answering any questions -- then don't.
If the questions (and you'll get them anyway) happen keep saying, over and over ... 'I am going to exercise my fifth amendment rights and not answer questions.' At some point someone will ask you if you want an attorney. What I said was, "I don't think I need an attorney, I didn't do anything wrong. Do you think I should have an attorney? Am I under arrest? Can I go now?"
I was at a collective in N. Cali delivering about 400 clones ... yea.
Standing out in the parking lot when the cop opened up that truck .... gasp. LoL.
The only exception I made to my no talking rule was when he said, "This is too much for personal use." I replied, "That's why I'm here ... at a collective ... isn't this where I'm supposed to take excess meds?" He didn't like that.
"I'm going to confiscate these as contraband. Unload your truck and put them up against the building there."
"Fuck no. I'm not unloading this truck. If you're going to rip me off, YOU unload it."
LMAO
There was a bunch of Explorer Police kids there, I call them Youth Nazi's.
They unloaded it.
They confiscated my babies, and let me go after about two hours of trying to get me to answer questions.
