So the guy asked you a simple question and you didn't answer it? In stead of simply saying Im here to pick up my kids you went full smart ass? I assume you are white by the fact I didn't see a video online of you being tased or body slammed by the cop. Just answer a simple question and move on equals no drama. Now he followed the book and made you sign in the way he is supposed to make everyone but doesn't bother with the people in the cars. You want attention now you have to deal with getting the by the book treatment when ever he wants to. It is too much drama for a simple question at a school. Congratulations you are now on a first name basis with Barney Fife that you don't need.
