Good job trooper! Having to make a split second decision, usually having very little information, takes a lot of guts.
The reason for this law, is that, as the current ban on texting is written; it is illegal for a police officer, firefighter, or medical personnel, to look at their computer while they are operating. As written now, to legally look at the information pertaining to the call, they would be required to get off the road, stop, then look at the call particulars. This takes up time that they will not be responding to the emergency.
