What I think about this story

what I liked the most about this story , is the courage of the officer as he risked his own life to save the others ; it is not an easy decision to take I mean he did it because it's his job but what a risk to take especially the guy was holding a knife and was completly insane so I praise this brave officer and people should learn from him I mean we should give a credit to those people who risked their lives to save ours and it is not an easy job at all so well done officer!!!!
