It's been a frightening few weeks in Southern California. On the heels of the mass shooting in San Bernardino came an email threat this week that shut down the entire LAUSD school system. 

Police deal with violent and stressful situations in their everyday work, but have the recent events made things worse? Or is it just business as usual?

Kevin Jablonski, LAPD's chief psychologist, says events like the San Bernardino massacre increase stressors in a police officer's environment.

"We can't lose sight of the fact that police officers, for all the service that they do to keep communities safe and protect people, they're still human beings," Jablonski says. And in addition to the pressure of the job, they have to deal with the same everyday stresses that the rest of us do.

In the recent aftermath of the incident in San Bernardino and the threats against Los Angeles schools, Jablonski says, "I think that it does bring it home. It makes it, in some regards, more real. It challenges them to the extent that they have to in fact contemplate the number of lives, if you will, that in so many ways they're responsible for rendering aid to."
