Textalyzer will just be a tool to be sure the driver is telling the truth or not. I remember getting pulled over because a cop saw me on phone. I could of said I wasn't and argued. But with something like this device they now have. It will make enforcing the law better right?

When you get in trouble with the law, (and the officer is a law enforcer) you lose. I understand there might be a privacy issue, but it is simply to verify if you were in fact using your phone.
