I remember when a member of the National Front (ie Nazis) stormed a public presentation I was doing and tried to start a fist fight while getting in my face.
Security escorted him out.
The man was angry, attempting to do a violence, likely dangerous. We de-escalated the situation and everyone walked away unscathed - as horrible as that was, the crucial part is everyone walked away without violence
And that was without a professional, highly paid, planned-for security detail in a public arena.
How is the security team not briefed on how to prevent engaging in violence when confronting streakers? Amateur hour imo. I feel like that should be the first item on the docket at the first planning meeting.
