Last week, the Washington Post published an opinion piece authored by Valarie Long, the Vice President of SEIU Local 32BJ, which represents approximately 10,000 security officers across the Northeast.

In the piece, Long recognizes the importance of the job that security officers perform each and every day, raises the need for improved standards in the private security industry, and offers her condolences to the family of Officer Johns.

Here's what she writes:

The tragedy at the U.S. Holocaust Memorial Museum was a painful reminder that private security officers often are our first line of defense and that these modestly paid men and women risk their lives to keep us safe. As we mourn Stephen T. Johns, we can honor his memory by raising security industry standards.

It's in everyone's best interest to ensure that security officers are well prepared to handle emergencies and are treated with the respect they deserve for their brave service.

No doubt, you've likely heard about yesterday's tragic shooting incident at the U.S. Holocaust Memorial Museum, where security officer Stephen T. Johns tragically lost his life.

The event is a bitter reminder about the importance of these brave men and women who serve as the "first line of defense against a terrorist attack," and the methods that can be taken to ensure their safety while on the job. All in all, there are more than 1 million private security officers in the United States - nearly twice the number of police officers.

On this morning's Today Show, the director of the U.S. Holocaust Memorial Museum, Sara Bloomfield, paid tribute to Officer Johns and commended the entire security team for their bravery and heroism:

"Everything happened yesterday as we train for these things. And as I think you've reported, two of our officers did attack this assailant and none of our visitors were hurt, so we feel that this actually worked extremely well, in terms of how many lives were saved in this incident. And again, we want to commend our officers who responded so well and pay tribute to Officer Johns, who also behaved so heroically in this incident."

In an interview with the Center for American Progress' ThinkProgress, Steve Maritas, the organizing director of the union that represents them, said the following:

"These guys are security police professionals, which is a whole different level of training compared to security guards...When they train these guys, they're trained on more of a terrorism level."
