In September, there was a controversial "live fire" with blanks "active shooter" training an hour or so away from Wilkins at a Bethel Park HS. Parents were pretty upset about the fact that it was using "live" blanks.
Training was done by A.L.I.C.E. - link and archive of their website is in the post linked above. (https://www.alicetraining.com/)
