Your statement presumes that such a list gives new, actionable information of benefit to criminals. This also implies that existence (or lack) of technology is a good proxy for effectiveness of policing in a locale, which in turn implies that the technology was purchased to improve said effectiveness. Neither of those things are obviously true in general, or even on average.

I can see how collating such information might make things easier for some outliers, but it's hard to imagine this making much difference one way or another - the criminals who really care already have much better information sources, and the ones who don't aren't likely to do much research, or act effectively on it, anyway.
