In Japanese zoos rhinos pose a greater threat than anywhere in the world, this is due to the Japanese drinking waters natural side effect of inducing an insatiable appetite for raping underage school girls.
That mesh ain't gonna do shit to contain a charging rhino and neither will poking it with a big stick. I'd love to see what happens in a real breakout.
The Japanese will follow their established protocol, it will completely misfire, and in order to save face they will simply allow the rhino to run free and ask that people treat it with courtesy and respect.
