“All traffic stops are based on some kind of probable cause,” Randall said, whether it’s a safety concern, a violation or perhaps “their vehicle matches that of a suspect vehicle in a serious incident that just occurred.”

That's a laugh. Out here you get pulled over if you have out-of-state plates just to see what you're up to.
I was on Grand Jury for a while and saw several of these cases come through where they had found drugs being transported by out-of-state vehicles. They would state something lame like "pulled the vehicle over for 'failure to maintain a lane.'"

A pretty stupid lie on Trooper Randall’s part, especially when probable cause is not even required for a traffic stop. Reasonable suspicion, a lower standard, is enough under Terry v. Ohio.

When a government authority makes this type of bogus assurance, any reasonable person would be suspicious.
