Nothing is wrong with carrying a copy of the constitution or knowing the law, but from the looks of it the guy who made this video purposefully the video to look like a victim.
His plan was probably this: Make a video, spew out all these laws, give the cop a hard time, make him look bad, then everybody feels sorry for him.
What probably happened before: This guy was driving really badly, cop performs a traffic stop, guy acts all suspicious, strong smell of weed.
Weed has been decriminalized at this point in many states, smelling a little weed isn't a big deal more. However If the smell is really potent, comes from the car and the trunk, then it is probably safe to assume that this guy hauling a lot of weed. Under the Carol doctrine he can search the car without a warrant. He can also cite the driver for smoking with a minor present in the back.
Bad cops exist, bad people that go out to abuse our rights exist, but the balance of power must be maintained.
