That's not what I read. The K-9 officer just came upon the scene.
Officers don't have the time or the desire to start checking every car on the highway with a K-9.
Most do not perhaps. Our rights protect us from the ones that do.
they either brought the dog specifically for a search, or he just happened onto the scene of a 6 mph sppedo ticket.
either way they obviously make the time to do these things when they want to. Honestly, its RARE to see a 'single' cop car on the scene of a traffic stop around here, so i would say they have plenty of time on their hands.
Now about that 'desire' thing, surely you dont believe that it doesnt make some cops feel like superman to try and save the world? Especially when the numbers crunch is only a week away...
