He didn't jump.
Instead, just to make a point he took of his shoe and threw it down form the 7th floor of the library. That is where he was dangling his legs from. He drank a lot of water, spoke on his cell, and talked animatedly to the people inside. Only once he addressed the crowd gathered below to say that JNU had no value for his life for the life of others. He got the police and the fire brigade and the tv crews in.
He didn't jump.
He came out looking like a martyr leaning on the shoulders of our student union president, he looked as if he had gone through hell sitting up there dangling one of his legs and his privates placed precariously on the window ledge.
I think he came down cause he had to pee.

Daddy!Daddy! It's just like you said- now the living outnumber the dead.
