I agree. Trulia already has a great crime mapping implementation that pulls from both SpotCrime and CrimeWatch and can even filter the data based on violent and non-violent crime. Having this data in a real-time, interactive, mobile app like Waze would be invaluable to motorists. I've heard rumors of a Microsoft patent that supposedly precludes implementing this feature, but it only covers pedestrian routing and explicitly excludes vehicular contexts. Since Waze is only used for vehicular routing, anyway, this should not be a legal issue Waze should be worrying about. If in doubt, consult Google's legal team. I'm sure they'll concur.
