Mass shooting(s) after Orlando (amended title)

[AdamG]

Now it does not help when the FBI get a citizen's call and appear to have dismissed it as a credible pointer.

Twice, within four months. Those Agents who failed to do their duties (and embarrassed the Agency) should be revealed to the public.

The F.B.I. received a tip last month from someone close to Nikolas Cruz that he owned a gun and had talked of committing a school shooting, the bureau revealed Friday, but it acknowledged that it had failed to investigate.
The tipster, who called an F.B.I. hotline on Jan. 5, told the bureau that Mr. Cruz had a “desire to kill people, erratic behavior and disturbing social media posts,” the F.B.I. said.
The information should have been assessed and forwarded to the Miami F.B.I. field office, the bureau said. But that never happened. On Wednesday, Mr. Cruz, 19, killed 17 students and teachers at his former high school in Parkland, Fla., law enforcement officials said.
The tip about Mr. Cruz appeared to be the second in four months, after another person told the bureau about online comments from Mr. Cruz that he wanted to become “a professional school shooter.”
