Spectra dominates most applications today, so kevlar is not used so much for ballistics vests. Additionally, the police are not the main customers, much is military. Third, kevlar is still used for cut-resistance but that will not show up in this data (nor would the military lives saved). So for these and other reasons, its intuitively correct to think that the invetion of kevlar has broadly saved more lives than what is mentioned. Or at least that would be my guess. Other people may have actual data to flesh the subject out.

I mentioned in one of my other postings in this subthread. I've gotten the impression, at least from one vendor, that mixed aramid and UHMWPE fabrics are common for law enforcement vests, due to their lower cost. And of course plain aramid is still cheaper, so is still used a lot.
