TGIF: This Week's "Weekend Knowledge Dump"

Just a reminder that Greg Ellifritz has a new "Weekend Knowledge Dump" for this week. Links to articles and videos on self-defense, including a couple on church security; health and dealing with injuries, including a detailed article on treating lacerations; various firearms and their use, including an article on the history of the tactical shotgun and evaluating .22 ammo for self-defense; and a lot more.
