When in Moscow I buy my gas there:
Pullman police arrested a 20-year-old man overnight for allegedly shooting another man in the face.
…
Pullman Police and the Moscow Police Department worked together to find Lawrence, who was arrested at a Tesoro gas station in Moscow a half hour after the shooting.
Just because they are across the state line from each other doesn’t mean they don’t have excellent cooperation. My understanding is the Washington State University Police (in Pullman), Whitman County (Washington), and Latah County (Idaho) police also work closely with the Pullman and Moscow city police. I’ve met a few of them, shoot with some of them and occasionally some of the sniper teams attend Boomershoot. All of seem to be good guys. Perhaps a little grumpy when one of their fellow officers gets shot (pictures here) however.
