Your traffic cops would otherwise be participating in murder investigations? My understanding is that these are different specializations and they don't overlap.

No real objection to "the data source is bad," but I think the solution there is improve the data source rather than willful blindness.

I didn't say "murder investigations". We have a very small number of detectives, who do not conduct traffic stops, but the overwhelming majority of our force (and of all the police work done here) is patrol, all of which do conduct stops.

We don't control this data! It's good to want things, but whether or not you think it's good that LEADS isn't good enough for real-time enforcement, it is not.
