Why use 2023, rather than say 1991 as your baseline? And 2024 as the year to use for reference (it is the last year for which complete data is available, after all).
And as for NYC, that wasn't dealt with on the Federal level but on the state and city level. And it left a power vacuum in the crime world that was soon taken up by others, which should have been dealt with rather than ignored. Who knew that policing cities of millions of individuals over decades is hard? Especially in countries where there are lots of weapons afloat.
As for the comparison with Haiti you make (and not to mention Iraq, as you did elsewhere in this thread): countries, especially countries at war and places like Haiti do not excel in record keeping. As such you probably should take the numbers reported from those countries as somewhat polished before being presented.
