Discussion of FLA ruling on guns in parking lots
A clear discussion, at last, in the St. Petersburg Times. The ruling apparently upheld rights of employees to have guns in parked cars, but not the right of customers to. The latter was keyed to how the legislature worded the statute, so they can amend it to cure the problem.
In the meantime, I wonder how a company would enforce against a customer anyway? They can always demand to search employees' cars with threat of firing them, but a customer has a right to tell them to go to. I doubt any commercial establishment that actually searched customers' cars as a condition to coming into the store would be in business very long.
