Watch this tactical analysis of the recent church shooting in Texas. Very insightful, very informative. And one hell of a shot from the old guy!
The key is to a) be armed, b) be aware, and c) do not hesitate to act when necessary. Both the usher and the first responder were suspicious, and both had the opportunity to put themselves at a tactical advantage by moving closer in the first instance and surreptitiously drawing in the second, but unfortunately, neither of them acted on their initial suspicions. It’s completely understandable, of course, but even so, their failure to act on their suspicions cost them dearly.
