I mean, those are FBI stats. Just because NY doesn't officially report stats to the FBI doesn't mean they don't have internal stats or that someone else doesn't have stats for NY. I'd imagine that if anyone wanted to do the leg work, that information is available by a FOIA request. But it would obviously take many man hours to examine.
But, maybe crime isn't down in NY or SF. What difference does it make? We all know that under the Constitution the Feds don't have general police power and that power is vested in the states and local municipalities. So, to the extent crime isn't down, it's really a local issue, not a national issue. So, my concern is whether New Orleans stats are correct and your concern is if Baton Rouge stats are accurate. Why do you care if the National stats aren't quite rite or the NY stats are wrong?
