I realize that the last update was only a few months ago, but I have updated my traffic stops paper again. It now includes a discussion of the United States Supreme Court’s decision in Navarette v. California, __ U.S. __, 134 S.Ct. 1683 (2014) (holding that a motorist’s anonymous 911 call reporting that a particular vehicle had run her off the road provided reasonable suspicion to stop the vehicle for DWI). Of course, I also blogged about that case here. The complete paper is available here. As always, it is a free PDF.
