My solution for dealing with onerous and numerous California laws and regulations that attempt to control every last waking second of our lives here is to simply ignore them. When they're down to human life functions like breathing and eating as a last frontier for taxation and regulation, that's where I basically draw the line. I do not consent and I will not obey. I am not a subject of the State. I am a sovereign human being. I am prepared to reinforce my rights with the Law and with Arms if necessary (thank you, 2nd Amendment).
You might think that these laws are enacted to assist law enforcement (btw, whatever happened to peace officers?) but as PB Bob pointed out its really just a ruse to make sure the good subjects of the King are paying their tribute. The same type of law was recently enacted for scrap metals after the spate of thefts that occurred during the 2008-2009 timeframe. If you bring in a load of scrap and the scrapman doesn't know you, he's required to record all of your identification, including copying your driver's license or ID and taking a thumbprint (no, I'm not kidding). You must also sign a written declaration that you either own or have permission to scrap what your brought in. I assume rectal exams are coming up next (no, I'm not kidding here either).
Fortunately, as someone who's been doing business with my scrapper for a long time, and having already been on file with them, and owning a "legitimate" (I don't like those kind of words because it implies someone who isn't running a business is not legitimate) scrap business of my own, I was spared all that nonsense. But don't be fooled for a second. This new regulation helped keep the dirty tweakers from profiting from their ill gains, but down the road (if not going thru legislative machinations as I write) they will use this information to tax scrap metal transactions. Just give it time.
Anyway, sorry for the rant but as someone who is on the front lines of this fight against increasing government tyranny I can't help but to speak out in the hopes of fomenting anger and resentment in others that haven't yet put two and two together. You either take a stand here and now or lose everything later.
