Why would you ignore that this is a map? That's the point - the data is now conveniently visualized as a map...

Someone's permit could be for business, which means the handgun,if they even have one, may not even be at the house.

True. And your argument would be further strengthened if you pointed out that some of these are 5-year permits and some are lifetime permits. So, many of these individuals may have sold their guns, died, moved out of state, etc.

Or worse, it's conceal and carry

CCW permits are very, very difficult to get in New York.

I know burglars may be low lifes, but they're also kind of lazy. The time it would take to thoroughly research a gun burglary could be sent going to another state and buying legal guns by the bundle.

I have no idea how likely it is that criminals would use this data, only that it's now much more convenient for them to do so.

Obviously non-felons have a much easier time getting guns. People who steal guns or buy illegal guns usually aren't allowed to buy them, most likely because they are already felons.
