Are you using Waze?
If you do a lot of driving, you should.
Find it in the Google Play store...
Its pretty handy for getting alerts about traffic blockages, rerouting, and the occasional speed trap.
(Saved my bacon twice on the way back from N'awlins last month...)
The po-po are making a stink because of that- they hate when someone takes away their advantage when it comes to revenue redistribution...
However they are covering it up with the "ZOMG, the crazy cop killers will know 'zackly where we are, so if Google doesn't shut down that part of the app, you're gonna see a rise in cop killings!!1l!" argument.
Does anyone else think this is a little over the top?
After all, if a cop killer wants to find cops, he can look under "Police Stations" in the phone book.
Or even "Dunkin Donuts" if he really wants a target-rich environment...
