That's been suggests before and not something I think can be easily done, but I've not tried this, so I'm not totally confident. The only way to tap "not there" is to have the police "ahead of you" on your route. So if they were running Waze, they'd have to be moving to tap Not There. They could have some coordination going on with someone else doing it for them, but I doubt they are going through that amount of effort.
In addition to that problem ... if they're just sitting there and not moving, Waze will shut down after the inactivity timeout (which is 5-10 minutes, don't remember for sure), so they'd have to keep re-starting Waze. Also, they would be polluting the speed data for the segment that they were last on before pulling off behind the billboard or onto the U-turn ... so Waze could potentially see that as a "traffic jam" and send you a different direction (thus adding to your trip time, but still keeping you from getting the speeding ticket that you deserved ).
They could use Live Map from a laptop... I highly doubt it though.
