Avoid Deny Defend. Training in how to survive a mass shooting can save your life in the statistically unlikely event you are involved in one. The Avoid Deny Defend program developed by The ALERRT™ Center at Texas State University can be done online. Be forewarned that the staged videos are very realistic and may be freighting, but could save your life : http://bit.ly/29XA2cY.
Not really. Any time something so dramatic happens, it is natural to be concerned. Keep in mind that hundreds of thousands of movies are shown every year without incidence. It is smart to be alert but the dds of something happening are incredibly small.
