Police use Breathalyzer, but now watch out for “Textalyzer”

Are police getting too much power? I know you have heard of Breathalyzer, a device used to determine if drivers are driving drunk. Well now they are considering “Textalyzer” this where a cop can see they last time you used your phone! 

With the "Textalyzer," police could get a roadside glimpse into whether drivers were texting, emailing, browsing social networks, or taking a selfie while behind the wheel.

Is this going to far? Tell me your thoughts!
