As you say, the stop was legit. Asking questions during the stop is also ok. Extending the stop by ten minutes to run a serial number with no probable cause or "reasonably articulable suspicion" is not ok.A-R wrote:BIG difference between vehicles and homes and courts have said so.
As for fishing, I dont disagree the serial # search could have been fishing (dont know enough to say for sure, but id say likely at this point) but the stop was legit (OP he admits he was speeding). If LEOs don't ask some basic probing questions when the make a legit stop/contact then when are they supposed to do so in order to catch felons/warrants, drugs, etc?
Oh would you prefer to go back to the good ol days of cops eating donuts and pretty much leaving everyone alone unless the get grossly out of line?
Probing questions are fine. Detaining people for longer than is required to issue the citation is not.
Side of the road isn't the place to argue it... a polite but firm letter to the chief would be my response.
