It isn't just Costco and it isn't just employees that call in bull$hit MWAG calls on legal concealed and open carriers. It happens all the time. Best case: A law-abiding citizn exercising his rights is detained by a cop who understands the law and moves on quickly. Too often, the ccw carrier ends up tasting pavement, being forceably disarmed at gunpoint, and cuffed. Worst case: See above.
It's unacceptable - all of it.
Yes, it is unacceptable and that's why COSTCO must be put out of business.
