The security guard was being held by the hair.
That reminds me of an incident 45 years ago when I was a student at the University of Oklahoma. I was on campus during spring break since home was 1,400 miles away. There had been a fire-bombing on campus that week. The campus police recruited students for security at night around the campus.
During the induction, one of the officers was giving an applicant a hard time for having long hair. The officer told him that it could put him in danger. I stepped in and pointed out that that was why policemen wore clippy ties so that a perp could not get a handle to pull. I had already looked to down to see that the officer was NOT wearing a clippy tie. He quickly moved on to another topic and let the guy with long hair, alone.
“The security guard was being held by the hair.”
Which is the prime reason Roman soldiers shaved and kept their hair short.
Which is why I advocate G.I. Jane haircuts for military females.
The consensus used to be short hair thwarted lice. It does that too. But perhaps there is the physical combat aspect as well.
