Family of a Parkland victim is suing the federal government - for neglecting to stop the massacre

The father of a 14-year-old who was killed in the Parkland, Florida, massacre says that the federal government could have stopped the murderer — and he's suing over it.

'Everybody failed'

Fred Guttenberg says that he got a phone call from an FBI agent who told him the government could have prevent the massacre but didn't.

Jaime Guttenberg was one of the 17 people killed in the Feb. 14 massacre Marjory Stoneman Douglas High School.

The phone interaction between her father and the FBI agent is detailed in the legal filing against the government.

“Are you telling me that if the FBI did not make a mistake and did their job a month sooner, my daughter would still be alive today?” Fred Guttenberg asked the unnamed agent.

“I’m afraid so, sir,” the agent reportedly responded.

The lawsuit cites several incidents where law enforcement failed to follow up on tips that evidenced a growing malice and tendency toward violence from the attacker.

In one incident, a woman who knows the attacker called an FBI tip line and told them, “I know he’s going to explode." She even warned that he might commit a gun attack at his school, but no one followed up on the tip.

“Everybody failed, and this is going to be the shooting where we hold people accountable,” said Guttenberg at a meeting of the Marjory Stoneman Douglas High School Public Safety Commission.

The family is seeking damages but does not state an amount they are seeking.

Guttenberg was also a part of a lawsuit against the gun manufacturer who made the gun used in the massacre that took his daughter's life.

Guttenberg also made headlines when he tried to shake the hand of Justice Brett Kavanaugh after one of the hearings for his confirmation to the Supreme Court, and Kavanaugh was ushered away by security.
