Surely you don't think all 25k porch thefts are performed by 25k individual people?

I’m sure they’re not but we’re talking about the statistic for unsolved crimes not uncaught criminals.

The point is you don't have to catch 25k people nor solve 25k individual crimes one by one.

You have to catch the much smaller number of people who are committing 25k crimes. One porch pirate will steal lots of packages.
