"Well your honor, the perp was in possesion of a Bic lighter but had no visible cigarettes or other tobacco products so I stopped him on suspicion of possessing marijuana. That's when he failed to produce citizenship papers." (Yes, that is a legal reason to stop/approach someone in Az and has been since Gov Ed Meacham's time in 90-91.)
First of all, that is NOT reasonable suspicion of possessing marijuana, and anyone who claims so is exaggerating or failing to mention OTHER relevant facts.
Furthermore, Judge would probably hit the cop with his gavel because the law doesn't say, "An officer can ask for immigration papers anytime he pulls someone over for something else", it says that the Officer MUST have
reasonable suspicion that the person is in the country illegally. A Bic lighter with no cigarettes
may be reasonable suspicious for having pot (it's not) but it is most certainly not reasonable suspicion for being in the country illegally.
Lastly, "Ev" (Short for Evan, and not at all Ed) Mecham was Governor in 1987/1988, not 1991/1992.
