Any thoughts on a five hour police response and the adequacy of protecting an unarmed citizenry?

It's not great. But we can't tell exactly from the article when he called the police or what he said to them, but given his claim that they went through the deadbolt in about ten seconds, there's a pretty good chance he called them after the burglary. After the robbers had left the scene.

In such a scenario, it's not entirely surprising that the police did not prioritize allocating graveyard shift patrol units to come out there to take a statement. Especially if the victim said anything to indicate that he didn't believe he was in continued danger.

Nor is it true that activists "don't care" about these scenarios. They just believe (with some evidence) that the weight of the harms is greater if you have lots of guns than fewer guns. Activists constantly tell people to wear their seatbelts at all times while driving - and that doesn't mean that they "don't care" about the incredibly rare scenarios where wearing one's seatbelt does marginally interfere with escaping a vehicle, just that they know (with complete certainty) that scenarios where wearing a seatbelt is worse for the driver are trivial compared to the vastly more likely scenario where it saves lives.
