From the article that OP linked to:

"Since Compstat was introduced, crime rates in New York City have dropped dramatically. From 1993 to 1995, the total crime rate declined 27.44 percent across the city."

National crime rates dropped as well in that period but nowhere near 27%.

Seems like national stats maybe lagged NYC a little, but from a slightly different range of 1994-2000 on this chart the drop was (eyballing) 35% for homicides.

This is so utterly compelling a rebuttal that I can hardly believe the original argument was made in the first place. You can't argue that tool X led to outcome Y if everyone had the same outcome without tool X, and in fact the evidence then leads to the opposite causality: tool X is useless toward outcome Y.

True, CompStat is not at all "widely credited" with contributing to the nationwide drop in crime. Even its contribution to NYC's drop is debatable: https://en.wikipedia.org/wiki/CompStat#Critique

not only nationally, but worldwide!

In Germany we have no "predictive policing" to my knowledge, and even cameras and so on are used conservatively given how privacy sensitive we ware. Yet we've seen the exact same development over recent decades.

NY police were working in Germany......... or
