Capt Bob:
I see you are in Florida, so I assume this happened here.
If so, a little history for you.
Back when the state was first considering the waiting period, law enforcement, particularly in southeastern Florida (read Dade County and close by) were very vocal about the need for the waiting period. Most other LE agencies were not so vocal or said nothing. A few opposed it.
Eventually, pushed by the media who trumpeted the law enforcement agencies' endorsement of the plan, it passed the legislature.
However, the legislature determined that they would NOT exempt law enforcement officers. A little "gift" ( read payback) for those agencies who were so much in favor of the waiting plan. Nothing was said, no heads up, just absolutely nothing in the new law making an exception for law enforcement officers.
It was hard for the officers from those departments to complainsince they weren't buying duty guns as they were furnished by their agencies, and the guns they were buying and waiting 3 days on were the same kind the other citizens wanted.
So, what's the problem (read sauce for the goose, sauce for the gander)? And, if they want to avoid a wait, all they need is to get a CWP permit.
Once in a while a LEO tries and sometimes succeeds in talking or even bullying a dealer into selling him a handgun without the wait, but not so often anymore (a well-known large LGS got caught in an ATF audit giving guns to people without the wait and without a permit. The LGS answer, that the customers were LEOs, didn't go over so well).
