"As the night progressed, according to the new dispatch records, callers became increasingly desperate, begged for help and warned that people around them were dying."

I believe this statement proves that the situation wasn't a gunman with hostages, all locked in the men's room, as they've been tryin to sell it.

Can't believe the gunman in a small room with these hostages would allow em to phone out and ask the cops to bust in. He wanted to call everybody on the planet before the grand finale.

Looks like there were a number of unhurt and wounded people in the back half of the club, and the cops wasn't gonna go into the back half to save em.
