Some interesting classes last weekend
The CUES For the Armed Citizen, focused on body language, facial expressions, to use as, well cues to possible motives of people we encounter. There was even a section on spotting suicide bombers.
The Trauma Self Care course taught what and how the student could treat themselves for trauma injury, such as gunshot wounds.
The Defensive Knife course, focused on how to evade, and disarm, and how to use a knife in self defense, including several force on force scenarios, once again proving you do need some space to use a gun, when it's in your face you'll have to resort to empty hands tactics, as there will be no time to get the gun out.
