Doesn't Princess have former British Gurkhas in security
I read about a riot that happened in Hong Kong when it was still under British Rule.
The Gurkhas were able to disperse the crowd quite qickly. The Gurkhas were all lined up in a row, and pulled their Kurkri knives out 1/2 inch, one inch ...
After 2 inches, the crowd realized, if they pull them out all the way, they will have to draw blood, so lets leave know before anyone gets hurt
