I work with stats. I think even very honest people with high incentive to tell an accurate story and good data have trouble with stats. Now add politicians and police and bad data into that mix with winner-takes-all politics at stake and the stats get gamed.
Also I believe my eyes and when I see crimes happening in my neighborhood I don't rush to "the stats" to ask them what I saw.
So we have stats, that's the closest we have to objective, but I guess we can't trust those. You say your anecdote contradicts "the stats", and I genuinely believe you. Sincerely, what's the alternative? Vibes? We gotta steer this ship (society) based on something.
How else do you condense down myriad and often conflicting datapoints of this complex human existence in order to get trends you can make decisions on?
But "what you saw" isn't necessarily representative of the state of things, either. Arlington, VA is (was?) one of the nicer places in VA; generally expensive, etc. When I drove through there, the van in front of me at a light was car-jacked, and the person in it chased down. I'm uncomfortable driving through Arlington because of that; even though it's not representative of the area. Admittedly, this was years ago... but the point stands. My experience is not representative of the actual facts.
