Sen. Dianne Feinstein, D-Calif., after another mass shooting, predictably wasted no time in demanding still more gun control legislation.
This week, a killer with a valid ID entered the Washington Navy Yard in southeast D.C., a military facility where 16,000 people -- mostly civilians -- work. He killed 12 people and wounded several others at the Naval Sea Systems Command headquarters, where 3,000 people work.
The suspect, Aaron Alexis, who was killed at the scene, was a 34-year-old former Navy reservist, employed by a military contractor after an honorable discharge. It is unclear which of the three firearms found near his body were brought in by Alexis -- or whether he got them from security guards after he shot them.
Early reports on the shooting claimed that Alexis used an AR-15 assault rifle, the same weapon used in other mass shootings. Turns out there wasn't even an AR-15 at the crime scene. Still, advocates call for more restrictions.
But Alexis' troubled background literally screamed: "Red flag! Red flag!"
Alexis, a native New Yorker, had been arrested three times from 2004 to 2010. The first occurred in Seattle, when he shot out the tires on the truck of a construction worker who had reportedly angered Alexis for "disrespecting" and "mocking" him. Alexis told the police he had an anger-fueled "blackout" and could not recall the incident. Alexis' father told the police that his son had anger management issues and suffered from post-traumatic stress disorder as a result of assisting "as an active participant in rescue attempts" of 9/11.
Seattle police booked and jailed Alexis for malicious mischief and according to their paperwork, sent the case to Seattle Municipal Court. But the Seattle City Attorney's office say they never received a police report, so they never charged Alexis.
In August 2008, Alexis was arrested on a charge of disorderly conduct in DeKalb County, Ga. "It appears he might have spent a night in jail," said DeKalb County Police Chief Cedric Alexander, "but ended up for forgiveness bond on a county ordinance." The reports did not indicate any weapons were involved, said the chief.
Then in 2010, Fort Worth, Texas, police arrested him for shooting his gun through the ceiling of his apartment. The bullet went through the floor above and came within a few feet of a woman living upstairs, according to the police report. Alexis told the police that the gun accidently discharged as he was cleaning it while cooking dinner, but the above-floor neighbor believed Alexis fired intentionally because he had complained to her several times about her making too much noise. Again, no charges filed.
