Selling to police departments can be quite lucrative. I know someone who sells "forensics" software. I won't say what it does but it's both basic and snake-oil-y at the same time. They are raking in big bucks. It's also not a market many in the startup world thinks about usually.

> California’s cops have become accustomed to the adrenaline rush of data and analysis that Palantir provides, and the more departments that join, the more addictive its products.

It's just a matter of making the software seem and look like like magic. Police departments traditionally are not very tech savvy, so they will readily throw money at stuff they don't understand. Well, not unlike enterprises but it's just more pronounced it seems.
