I dont know, lions are pretty friggin mean. if that glass wasnt there the lion would deff kill those people. you cant even go close to wild lions, way to risky.
there was a guy who recently went down into a tiger cage at some zoo with a rope. the guy was yelling that if god existed he wouldnt let him get killed.
as soon as he went in, a tiger casually walked over and tore out his throat.
