The problem with event sec (and I ran large events for a decade) is that organisers often dont treat you like you're anything but a bunch of fuckwits and dont tell you anything about planned stunts or anything beyond "Dont let anyone past this point without a pass" asking questions and wanting to be in the loop often gets you told to "do your job" which is why I was very anal retentive about what was and wasnt our responsibility in our contracts and what we were/werent liable for. Often the "talent" or people attending will decide they want to do something off script and you have to take a moment to decide wether or not to crash tackle someone somewhere they shouldnt be who might also be a keynote speaker or the headlining artists manager... its almost always a shitshow of not enough info. I have a lovely story about a bass player for a band not wearing a lanyard and starting a fight with two of the security when they wouldnt let him back stage... theres an NDA involved though because he broke one staff members cheekbone before getting knocked the fuck out.

The absolutely idiotic part was taking him to the ground, that outnumbered and not being aggressive it was unnecessary. Once it goes to the ground it almost always turns into a shitshow.
