It used to be that if a police stop was unreasonable, evidence found after that illegal stop was excluded from a case when successfully challenged in court. This week, however, the U.S. Supreme Court ruled 5-3 that evidence from an unreasonable stop can be retroactively validated by a pre-existing warrant.
The ruling seems confusing and of little consequence to many. However, it's actually a big deal because millions of people have outstanding warrants for small infractions. Also, the decision shifts the angle on time and evidence in criminal cases. In the words of one dissenter, "Do not be soothed by the technical language." Let's consider the opinions -- majority and dissent -- and why this case is significant.
