Active Shooting Survival
A good video on surviving an active shooter survival. One point that is notable in this video is that, even if you are armed, you should hide and only engage with the shooter as a last resort. To some, this may seem cowardly. But, obviously, if you want to have the best chance to survive you should think twice about attempting to fight back.
Telling you to run away and, even if you are armed, to not confront an active shooter is controversial. However, this video is about surviving an active shooting. Simply put, if you hide, you will most likely have a better chance of survival. This video is about surviving and any judgements are left up to the viewer.
