The footage shows Clay Duke, 56, spray painting the letter 'V' in red paint on the wall inside the school before ordering everyone save six male Bay District school board members to leave the room.
Then, as news cameras that were filming the meeting continue rolling, he is seen raising his gun and pointing it straight at one board member from just a few feet away.
'Please don't,' the man can be heard saying on the footage. 'Please don't.'
Duke fires - but misses, and the board member crawls out of the room on his hands and knees as Duke opens fire.
Moments later, police said, after he was wounded by a security guard, Duke turned the gun on himself. He was declared dead last night.
The astonishing footage also captures one brave woman creeping back into the room behind Duke and hitting him with her purse before he shoves her to the ground.
Duke had been sitting quietly during the earlier part of the meeting, witnesses said. But when it came time to open the floor, he stood up from his seat, walked over to the wall and took out the can of spray paint.
