Venue Safety

Post- Paris
While going into work at the local venues across DC, I've become increasingly aware of those who are familiar faces in our production team, and those who are completely unfamiliar and unknown to me. At what point do we raise an alarm and ask who these people are? Sometimes simple spectating now, has become a fear in the workplace. 

I was cruising through the Facebook interface and found this fantastic article regarding performing venue safety, and I have to say- I would strongly agree with the article. There are very horrific images in this, please use caution when viewing.  http://www.jimonlight.com/2015/11/20/what-if-im-attacked-at-work-a-crew-primer-part-1/

What is it that we can do to keep us all safe? Is the next stop TSA style screenings just to enjoy an evening? When do we get "normal" back?
