I have extensive knowledge of the 4th amendment, at least for a lawyer. I never made any blanket statements regarding anything. I was discussing a specific incident and I believe that you've attributed a quote in your posting to something that I never said.

Of course a lot can escalate a traffic stop into something much more, such as things you see, smell, hear, answers you get or don't get, outstanding warrants, etc. However, if none of that happens, the initial traffic stop has a limited life span.

Police searches incident to traffic stops wasn't the point of my story. I was merely pointing out that police-civilian lying can often be a two-way street and I am sure that neither group appreciates it very much.
