“How to protect yourself during a mass shooting”? Be the mass shooter, preferably white, male and Christian.
I do want to ask the writer what problem they intend to solve. Telling a few people some fairly random tactics that most will never practice, with some small probability of increasing their own chances of survival, or preventing mass shootings from occurring at ever increasing frequencies and amplitudes in the first place?
I’ll bet the writer is an NRA shill, one of the more “reasonable” ones.
