What has this world come to?

I was surfing youtube and came across this video today. My first thought is what has this world come to? There was an office full of people and only one person came forward to take this guy down. After 911 and all the school shooting that have happened, how dare people just stand around and watch someone hurt people around them. I'm a women and I know I would be one of the first up there to take that guy down!! I would never allow one person to take hostage over me even if it meant serious injury or death to me. We need to stand up and not allow this kind of crap to happen in our schools, work place or our country! Too many people are getting away with uncontrolled behavior and making excuses for their actions. Get over it!! we all have screwed up lifes... its not supposed to be easy.
