A local unit of government shall not impose special taxation on, enact or enforce any ordinance or regulation pertaining to, or regulate in any other manner the ownership, registration, purchase, sale, transfer, transportation, or possession of pistols or other firearms, ammunition for pistols or other firearms, or components of pistols or other firearms, except as otherwise provided by federal law or a law of this state.
They cannot impose any regulation pertaining to the transportation or possession of firearms. Requiring a police escort is an extra regulation not accounted for under state law and therefore they cannot require it. However, I suppose if they found out about the pistol and then a police officer followed you around without interference, then I would assume that's within the rights of that officer to do... I would think it would cross the line if they stopped you and made you wait for the officer and didn't allow you to go about your business until he arrived.
