Many states allow any normal person to use a device for emergencies, reporting accident, dangerous driver, etc. It isn’t like they are sitting there on Facebook, a lot of necessary information goes through that computer. Many departments also utilize their phone for official business...so them on their cellphone doesn’t automatically mean they are texting their girlfriend about their date night. As far as speeding etc., again, there are many reasons they will drive fast etc. and are actually going somewhere in a hurry. Also driving faster than the flow of traffic is a way to make contact with as many motorists as possible. In some areas there are enforcement officials specifically looking for distracted/aggressive drivers. How do they catch people on their phone? Coming up from behind and passing on the side. Do some text and drive? Yah. Do some drive like douches? Yah. That isn’t automatically the case in those situations though. Watch some LIVE PD in your free time and you will quickly understand some of the stuff people complain about is them trying to respond to calls. I was watching an episode the other day and the officer had to use his phone to use as a GPS. I’m sure any other motorist would assume he was trying to text and drive...really was just trying to figure out how to get to the scene.
