A few months ago, in the sleepy little town in Decatur, Texas, a local man was arrested for child pornography. Normally, I would applaud such a thing, however something troubled me as I read the local newspaper's account of the arrest. To paraphrase, it said that "the arrest was made using information gathered from the man's cellphone during a suspected DUI stop".
I had never heard of someone's cellphone being searched during a routine traffic stop, even one for suspected DUI.
Today, I read an article on The Truth About Cars which addressed these concerns and featured the device used to accomplish these searches. It didn't ease my concern.
