Probably. While everyone here knows that GMRS is not what the FCC refers to as "amateur radio," I'm betting the legislators, who probably don't know an anode from a cathode, intended to exempt anyone with an FCC license. That the text fails to do that is a matter of definition; the old intent-of-the-law vs letter-of-the-law thing.
Same for law enforcement. I'll bring my GMRS license next time I'm in PA. "Look officer, here's my FCC license."
