back in 1986 i was in the boston subway, the redline at park street.
there is an island in the middle and a train on either side.
i had a camera with me, doing a little street ( well underground ) stuff
and a drunk fell down the stairs and pushed someone into the tracks
he missed the 3rd rail but there was a train coming .. i dropped my camera and ran to help
the guy ... a t policeman had already jumped in the tracks and pulled the person out ...

i can't imagine how a photographer or anyone wouldn't jump to help someone in distress
what a lame world we live in ..
