Nightmare on Ogden Street

Walking back to my studio from a shoot today I came across this...

Glass been smashed, belongings on the road below, a woman with blood on her face walking around on the footpath shouting...it was terrifying.
The police arrived quickly and the street filled with onlookers.
It's amazing he didn't fall or jump. At one stage he was hanging off the broken window frame.
My heart was pounding and yes I took a few frames while I debated with myself if it's the job of a photographer to record the world around us no matter what or am I just profiting from some poor souls misery.
