Trapped!

Yesterday, a group of people were trapped inside the elavator for almost 2 hours. It's such a huge crowd watching them. On that time you can have a peep girls undies from foyer if you want to! =)

The firemen came but all of them already escape from the elavator. I am wondering what's the purpose they come? And they late for 2 hours? What if someone died inside? Can they be trusted?
