I don't think "acting like a dick" constitutes legal probable cause. However if you're acting that way, cops have ways to make your life more difficult. Most of those ways are improper and can come back to bite them, but they usually don't. I'm actually glad people like that kid take the time to remind cops of the way things are legally supposed to work. They just shouldn't be surprised or upset that it's a hassle.
