I never saw that film but it must of been pretty entertaining for the cops to show up. I take it you were in trouble with the community standards in your house rather than with the law. The movie theater probably didn't get in any trouble about you being there.
The thing about your story is the cops, really had no reason to ID everybody. Did anybody get arrested? I could see maybe the manager of the theater but other than that not even you being underage, another violation of liberty on display in Spokane I'd say.
Thanks for checking in and greatly appreciate the support and the story.
