I mean the video starts off with this:
Driver: Hi, What’s the nature of this stop officer? (twice)
Officer 1: Can you roll down your window?
Driver: You can hear me right?
Officer 1: No, I can’t hear you.
I guess that's better than "if you don't I'll break it" like they said to Angel...http://www.nctimes.com/news/local/escondido/article_f0969a83-229c-57c1-be70-be71a37c17ee.html?mode=video
Another gem @ 2:29
Officer:Driver, this isn't funny
Driver: It's unconstitutional though
Officer: GOOD, walk up there I'll show you your constitution!
Maybe he never got the news?
This is a scenario that was never thought of? No procedure for handling this type of situation established? No training for officers on how to conduct checkpoints besides briefing prior to it?
