Listen, the feds can and do use ANYTHING to get you ONBOARD in their system with INTERSTATE commerce. Once you are in with that, then everything else goes fed with it. Keeping all your selling in state and that is cool. EXCEPT that they are going to get you on interstate commerce for the raws, THEN everything else goes in with it!!! Let me give you an example of how the feds can and DO get you into the fed system!! Guy goes to jail, (true story) he is SKATING on the charges of Felon in possession of a firearm because the feds used illegal surveillance on a telephone pole outside the guys house to get the footage for this possession of the firearm. So, on the day before the guy goes into court where the judge is slated to "throw the case out" the guy makes a call to his lawyer on one of those "Jail Phones" that has a recording telling the person called to press this number or that to accept... Well he calls his lawyer and his lawyer tells him, okay man, tomorrow when we walk into court you will leave a free man. I worked this thing out for you and so this is going to cost you 60 racks. Dude tells his lawyer, man you are smoking crack!!! I didn't need you man. They had no warrant for the camera that was their basis for the possession, and with or without you I would have gotten off anyway. Lawyer tells him, look... say what you want but I want 60K, and if you don't pay, I will put a lien on your house and property. Guy tells his lawyer, if you do that mother fucker I will kill your dumb ass!!! Feds charge the guy with interstate commerce and terroristic threatening something maritime in a territorial jurisdiction something or another and convict and sentence him to 5 years IN FED!!! How did they do that? Because the company that owns and transmits those jail calls from that company that the jail uses for those particular phones was in ANOTHER state and when he made that call they claim that the call was/is diverted through that company switchboard FIRST to that companies HOMESTATE then back to his lawyer that was in HIS state but since the communication went out of state to get to the lawyer it was interstate commerce.
ANOTHER EXAMPLE to show you that your idea will not work!!! The feds will take ONE bottle of BB bought out of FLORIDA that was bought and then shipped to you. And THAT (if you don't live in Florida) will cause them to make it an interstate commerce then the whole lab and selling part goes along with it to the feds.... You understand? It will go feds ANYTIME the dea wants it to cause they will make it!!! AND, they will terrorize and arrest ANYONE in or around you INCLUDING 90 year old grandmothers or whatever EVEN if they have NOTHING to do with it JUST to get you to take the plea REGARDLESS of how strong your case against them may be cause let me tell you, they are DUMB when comes to investigation!!! That why they have SOOOOO many rats. To do the work for them cause MOST them are dumb ass mother fuckers and I mean DUMB!!! They suck at their job SO bad that they resort in 80% of cases to INTIMIDATION of ANYONE around you to get what they need to prosecute you!!!!
So no, you're not safe from feds when/if they want you!!!
