Considering that flashing your headlights to warn oncoming motorists of speed traps has been ruled by at least one court to be speech protected by the First Amendment, you have to think that an app like this would too.

If Congress or a state legislature tries to ban these apps, I think the laws will probably get overturned. However, if Apple decides that they think these apps are in poor taste and shouldn't be part of their ecosystem, I'm fine with that. They've blocked apps that are far less offensive to me.

The other interesting question is liability. If a driver were to use one of these apps to circumvent a DUI checkpoint and then kill or injure someone in a car accident, I wonder if the app maker (or Apple?) would bear some liability. I don't think that free speech would offer much protection in this kind of case.
