Good question. Many times you just have to let them walk unless you can develop probable cause to search in some other manner. Examples might be a crack pipe in view on the car seat, drug odors, drug manufacturing gear in view. The search would then be incident to arrest and the scope of the search could potentially be even more limited. Locked compartments are typically off limits. With consent you have to warn the subject they can refuse and they can tell you where not to look and stop you at any time. I would have liked more detail here to see what if any info the deputy had beforehand. Without consent here I was wondering if he had enough to get a search warrant.
Thanks again.
I often get the feeling in local news reports that cars which have been stopped and in which drugs were found were known ahead of time to have those drugs, especially in a situation where a drug enforcement team is involved.
