Do they enforce rules, what is and is not under their jurisdiction? How much is left up to EP's?
For example at a USASF sanctioned event, which was outdoors, there were teams warming up stunts on concrete or grass. USASF rules state this isn't allowed and all participants must practice on correct performance surfaces. But nobody stopped them, even though there were multiple event staff within 10 feet. So whose job is it? The USASF wasn't there to say anything, and the EP did nothing. So nothing got done. But someone could have died.
It seems like everyone passes the responsibility off to someone else, and in turn nothing EVER gets done about it. Don;t get me wrong, we've come a long way, but we've got a long way to go to achieve sport status
