No it is not the same. It is not even close. Driving is an activity licensed by the state. What an officer can or cannot do is well defined in policy and law and Case Law dating back decades.
Running the SN of your property he comes into contact with outside the course of a lawful investigation into that property is much different. Whether it is your gun, your stereo, cell phone or whatever, possession of these items does not require a state license, and what an officer can do when he comes into contact is not well defined, which is why we are here discussing it.
Can he run the SN of your gun?
Can he pull out the head unit of your stereo and run the SN?
Can he make you unlock your phone to get SN and run that?
All reasonable questions.
Actually yes, Prouse vs US, which precludes the officer from stopping you in the first place to check your ID!
Sharkey pretty much covered my responses.
Do you mean Delaware v. Prouse, high speed? That case law prohibits a stop without reasonable suspicion to check an ID. Pretty sure it has been established the deputy had a lawful detention (and probable cause) due to the violation of Texas Traffic Code, per the OP's description of the stop.
If you are going to throw down case law, and try and make a reasonable argument, study harder.
