Don't assume that just because you have a printed copy of the law with you that the officer will not remain intransigent. In one of my encounters, the officer was so offended that I tried to show her where the law stated that SHE could not trespass me from Target that she went to her vehicle, pulled out her tome of Alabama Code, and tried in vain to look up the pertinent section.
I stood my ground and demanded a supervisor. In time, the officers (five of them) arrived at the conclusion that they could not trespass me. So they demanded that the manager do so. The manager called someone at corporate, and then told the officers, "No."
I know I risked a "ride." But at that particular point in my life, I had a LOT of time on my hand and apologies on file from the Deputy Chief and the City Attorney for the previous time their officers displayed woeful lack of knowledge of the law. That stop at Target was the LAST time Montgomery PD ever tried to stop me (or anyone else to my knowledge) for OC.
Be a Madisonian.
It finally happened. I have now been accused on OFCC of both being a cop-hater and then a cop-lover! Therefore, anyone making either accusation must not be paying attention.
