Meanwhile - admist all the foo-fa-raw of last weeks' RSAC 2017 - came very good physical security new's of a fascinating kevlar and aluminum origami-based ballistic shield (developed by Engineers at Brigham Young University) that stops .44 calibre magnum slugs. Very good news for law enforcement, and other organizations (think schools, other civilian government organizations, military, businesses)
The design is able to protect multiple people at one time and folds down to a compact shape. Utilizing the Yosimura Origami Crease Pattern, it currently tips the scales at a paltry 55 lbs. (25 kg).
