I am going to step out on a limb here and suggest that laws against [insert activity] while driving are stupid. It is tantamount to saying, "If I can't manage to walk and chew gum at the same time, then it should be illegal for ANYONE to walk and chew gum at the same time." Seriously, all the negative actions attributed to talking, texting, eating, drinking (alcohol or non-alcohol), reading, fussing with children, getting fellated (unfortunately, yes, I have encountered people doing this on the highway), or any other distraction while driving are already punishable acts, much in the same way that I do not believe in any such thing as 'gun crime' since the crimes in question are illegal regardless of the hardware used to perpetrate them. Punish the actual misdeed, not the pre-crime which happens to be the battle cry du jour.
I would also have to ask what harm is being done if a uniformed officer cannot clearly see erratic/dangerous/reckless driving without having an officer pose as a bum to catch people texting WHILE STOPPED AT A LIGHT. I would be much more concerned about their attentiveness WHILE ACTUALLY DRIVING.
My only issue with those that are texting/tweeting/face booking at the light......Please move when the light turns so we can all get through on the green.....please.
