The shooting happened last November. Deputies were called to the home after Michael Blair threatened to commit suicide.
Blair was shot 11 times. The family says the very graphic video should lead to a federal investigation of the deputies involved.
Blair's family said the 26-year-old was a suicidal, paranoid schizophrenic. When Blair locked himself in a bathroom, his family called 911 for help.
"He's got a knife, he's got a knife, he's got a knife," the deputies are heard saying in the video.
Everything changes as the knife is discovered.
"Stay down, stay down!" the deputies shout. Blair pushes the door back.
"I do not want to shoot you. I do not want to shoot you," a deputy said. Then, they begin Tasing him.
"Keep Tasing, keep Tasing, keep Tasing. Drop the knife! Drop the knife!" deputies said.
The deputies ask him to drop the knife at least 50 times, but he refuses, and eventually appears to lunge towards them.
A deputy opens fire. Blair's mother cries and yells "You killed him!"
Since this incident, the deputies have been cleared of wrongdoing by sheriff's investigators, the Texas Rangers, and a grand jury.
But Blair's family says this is murder.
"All that we're asking is that someone recognize what we recognize. That was brutality," said Blair's mother, Kimberly Blair Olaniyi.
For some reason, Blair's family hasn't shared the tape with investigators until now.
"These cases are always lied. And truths are not told. And so that tape was held until they would finish their 'investigation,'" said Quanell X, a community activist.
The LAPD has a special mental health unit to deal with these types of situations. Houston is changing its procedures and increasing mental health training for officers after this incident.
