No security & no guardrails seems like really shitty working conditions. Whats to stop irritated fans from getting into the ring and beating down heels? If there's no security, there's probably no metal detectors or frisking of people coming in to the show. I think that it is a joke that the wrestlers have to wrestle & do their own security.

Umm seriously? One word bro; Mexico. Freakin' Vampiro was kidnapped for a few days by drug dealers a few weeks back, they don't play there man.
Seriously though wrestling is taken more seriously there than in the states. While they wont have metal detectors and shit (Again it's Mexico) but I imagine one reason they don't have guards and guardrails to the point of WWE/TNA is because there's not as many idiots at those shows as there are here. I bet for that one dumb mexican who tried to take the mask there's 100 drunk rednecks per show that say to each other "I betcha I can take one them there wrestlers, this shit is fake anyway." and would climb into the ring if given the chance.
