Ok, if you’re thinking laser guns that would be pretty awesome but no – this is however something which is all in all a lot more useful – been working on documents and website designs for 3D Laser Mapping, who are in turn supplying laser scanners for the police – these scanners are pretty cool, basically allows them to record a scene, such as a car crash on the M1, they scan it all within a few minutes then are able to take this away with them to do there measurements etc and determine the cause of the crash and what not. This means the road can be cleared quicker, saving a lot of lost revenue and time from the hold ups etc. Here’s a link to a fairly recent article covering the matter.
