I suppose I better explain the title of this blog - Police readers will no doubt "get it" straight away, but the only person I have shown this to is a non police type, and her only comment was "It's a stupid title. Why not call it the Policeman's blog?" http://coppersblog.blogspot.com/
For every call created in the world of Policing, there has to be a result. This does not mean that we have to arrest a person from every call unfortunately, but means there needs to be something on the computer to justify why we've stopped playing with that call and moved on to pastures new. "Area Search No Trace" is a common result for calls, throughout the UK as far as I'm aware. Youths hanging around on the street corner? "Area Search No Trace." Sounds of a gunshot, no persons seen? "Area Search No Trace."
Sometimes it means you've driven past the incident location and seen nothing: "Abandoned call from telephone box, Pelican Street, sounds like kids messing about." You know it'll be ASNT before you get there, but you still go to make sure.
Sometimes it means you've been throwing yourself around an area trying to find a couple of burglary suspects, with the furry land sharks and chopper coppers all trying to help (and unable to due to a bunch of overexcited response team officers messing up the scent and getting in the way of the chopper's magic night time camera).
The beauty of the result is it can be used for so many calls. The "joke" in the title of this blog is the twisted way of saying it, "Area Trace No Search," which obviously has a slightly different meaning. It used to get a snigger or two and people would get the implication, that this was a quality call from start to finish. In these more modern times when control room staff are supervised heavily and without discretion, and when every transmission is recorded for further alnalysis, you have to be a little more careful.
Quite often now control staff will put exactly what the officer says on the CAD. Which isn't so much of a problem with Area Trace No Search, but when an officer pops up to give a result and says "he was looking to get arrested" then it's liable to be written on the cad "Subject asked to be arrested."
And don't even think about using the LOB result...
