Police reports aren't the only source of data. If this was a widespread impact then there would be other sources of data that could be used to build this case.
Additionally, we cannot make policy decisions on "just trust me, my friend said...". Maybe we can't get a perfect signal, but if you are going to challenge the prevailing data, I expect you to bring something novel beyond vibes. It doesn't have to be perfect, but a single anecdote plus "I believe it" is not sufficient to oppose what the data we do have is consistently saying -- crime is lower in Seattle, and has been consistently lowering over time.
