yes, I've seen these before.
It would likely have not ended well for the pranksters....
I attended an "initiation" for a group. Part of that "act" was that one of the participants attacked another member of the group. As one of the people "controlling" the entire days events said afterwards, "They've NEVER in 30+ years had someone respond so swiftly and forcefully to STOP an attack on another member".
I body slammed the attacker and bruised two ribs and knocked the wind out of him so bad that he couldn't breath for about 1/2 hour. They took him to the ER to make sure he didn't puncture a lung.
So these are VERY controlled or very staged.
