Pasco said. 'There's no control over who uses it. So, if you're a criminal and you want to rob a bank, hypothetically, you use your Waze.'"
What about the non-criminals who want to know where the police are so they can get some help from them? Or what about the non-criminals who want to know when police officers are blocking a side of the road, or dealing with a traffic situation? If they really don't want to be bothered, they should just drive unmarked cars, make their phone numbers unlisted, and institute some kind of paywall for their official web sites.
Instead of removing information from Waze, they should just be adding information to it with their own api. They could transmit the gps location of their marked cars in real-time (like bus systems now do with the nextbus api). When responding to a call, they should just send the person who called a real-time update of their estimated arrival. And when there is a bank robbery, they should just flood the Waze api with virtual police officers everywhere.
Not only that, but if the police could try to crowdsource the effort of looking for bank robbers, child abductors, or the obvious-looking drunk drivers, through Waze instead of overburdening the outdated the 911 system, that would help them prioritize and weed out most of the false positives in real-time.
