See Something, Say Something 

We’ve all seen something that made us pause and think, “Should I say something?”  Very often, we don’t. We’re concerned about looking silly or over-reacting. 

This video (English, Spanish) from Homeland Security doesn’t contain a great deal of new information. What it does do is make you stop and ask yourself, “Would I have reported that?” 

And, it will make you consider what the consequences might be if you had not.  Managers should take action if employees report something suspicious.  If we don’t, we are ultimately responsible for any harm that comes from neglecting to do so.
