There are times when info & assignments need to be non-radio. Lights & siren are not always used for a reason, sometime surreptious arrival is key. Sometimes time is of the essence and pulling over is not an option - kidnaps, medicals, armed home invasions where a Mom & children are raped & killed - this is REAL life.
If I give out the address of that over a radio, the media gets it, they are there before I can get a team together to set a perimeter, what do think happens? If you think this is not true - you are naive.
A road stop, is done with a pull over, but not all things cops respond to are a simple roadside stop.
Okay I am done with this because I see the handwriting on the wall, it is a non-arguement. It was really not a question to which an answer was expected but a chance to diatribe the evil of cops & cell phones.
BTW that Tpr in IL should not only not get his pension he should be in jail.
