Note it'd basically be their job to lower that number, so no wonder they're incentivized to feign it's not an issue. And typical lawyer speak is "That didn't happen, and if it did we didnt cause it, and if it did happen and we caused it then it's not our fault" it prototypical legalese (not they're a lawyer too)
Anecdata here, but after reporting 2 crimes in SF and hearing the police do nothing about it, I stopped reporting. I suspect their data is entirely broken by underreporting. FWIW I've also anecdotally heard, and observed similar in Austin which, for example, their roads feel more like being in a MadMax movie than orderly transportation.
