Why San Bernardino shooting was a different kind of attack
Since the church shooting in Charleston, South Carolina in June, we have now led the broadcast with a mass shooting -- on average -- once every four weeks.
But what happened Wednesday in San Bernardino was different.
"This is crazy, there's just too many shootings," Mark Scroggins, whose daughter works in the building, told CBS Los Angeles.
"There's too much bad stuff going on here," Scroggins said, just after finding out his daughter was okay. "I mean you hear about it, but this is just insane."
Wednesday's shooting was the seventh major mass shooting in the U.S. since June.
Just last week, three were killed in a Colorado clinic.
In October, a gunman left nine dead at an Oregon community college.
In August, two journalists were killed on the job in Virginia.
In July, two people were killed in a Louisiana movie theater, and five servicemembers slain at a Tennessee military facility.
And in June, nine people were killed while worshiping in a South Carolina church.
But those shootings were all were by lone gunmen who then either were killed by police, killed themselves, or were taken into custody.
Wednesday's mass shooting, with three suspected killers, including a woman, was something new.
"This is different. This is now an organized, multiple offenders, mission-oriented shooting with maximum lethality being the goal," said Mary Ellen O'Toole, a former FBI profiler. "That's different from anything that we've seen before, more in line with what we saw in Paris."
