Until yesterday, we had a relatively clear rule for police to follow: an anonymous tip must be corroborated before it rises to the level necessary to seize a person. Then the Supreme Court decided Navarette v. California. Interestingly, the 5-4 majority opinion was written by Clarence Thomas, with the dissent penned by Nino Scalia. Now I realize that people think I’m loopy for not hating Nino as much as I should, but it’s cases like this that should remind us of why he’s so much fun on the Court.
The majority held that an anon tip, of the sort that once needed corroboration, doesn’t really.
By reporting that she had been run off the road by a specific vehicle—a silver Ford F-150 pickup, license plate 8D94925—the caller necessarily claimed eyewitness knowledge of the alleged dangerous driving. That basis of knowledge lends significant support to the tip’s reliability.
There is also reason to think that the 911 caller in this case was telling the truth. Police confirmed the truck’s location near mile marker 69 (roughly 19 highway miles south of the location reported in the 911 call) at 4:00 p.m.(roughly 18 minutes after the 911 call). That timeline of events suggests that the caller reported the incident soon after she was run off the road. That sort of contemporaneous report has long been treated as especially reliable.
Another indicator of veracity is the caller’s use of the 911 emergency system. A 911 call has some features that allow for identifying and tracing callers, and thus provide some safeguards against making false reports with immunity.
