That ‘44% Crime Drop’ Stat? Here’s What It Doesn’t Tell You

The video above highlights a bold claim making the rounds: that Flock Safety’s ALPR cameras deserve credit for a dramatic drop in major crime in San Francisco. It’s the kind of statistic that spreads fast online because it sounds definitive. But for anyone who cares about how surveillance decisions get made in their own city, the real story is in what a single percentage doesn’t explain.

Correlation Isn’t the Same as Proof

Crime rates move for dozens of reasons at once — staffing changes, weather, economic shifts, policy changes, even how crimes get classified and reported. When a company that sells the cameras is also the one promoting the statistic tying its product to falling crime, that’s a reason for more scrutiny, not less. None of this means ALPRs can’t play some role in investigations. It means a single before-and-after number, without independent analysis of what else changed in that same window, isn’t enough to settle the debate.

Why This Matters Beyond San Francisco

Claims like this get used nationwide as a sales pitch to city councils and police departments deciding whether to install camera networks in their own communities. If residents and local officials accept a vendor’s own framing at face value, it can fast-track surveillance expansion without the independent evaluation that a permanent addition to public infrastructure deserves. ALPR systems log the movements of everyone who drives past them — not just suspects — and that data can sit in databases, get shared across agencies, or be accessed well beyond its original purpose.

What Everyday People Can Do

You don’t have to be an expert to ask good questions. Ask your local police department or city council for the actual data behind any crime-reduction claim tied to camera systems — not just a percentage, but the full context and an independent review if one exists. Ask how long footage and read data are retained, who can access it, and whether there’s public reporting on misuse or mistakes. Check whether your area already has ALPR coverage on the map, and read up on how these systems actually work before your city commits to expanding one.

The Bottom Line

A dramatic statistic makes for a great headline and a great sales pitch. It’s not a substitute for independent verification, public data, and real oversight — which is exactly what communities deserve before surveillance infrastructure becomes permanent.
