This is ALERRT. That stands for Advanced Law Enforcement Rapid Response Training, something created here in Texas two decades ago. Its active-shooter courses have become a federal standard, and now Texas is requiring all its cops to do 16 hours of this training every two years. The courses are updated often. For instance, trainer Randy Knight tells this class that research is showing that there's rarely a second shooter. So once cops have stopped one killer, they shouldn't leave wounded people behind to go looking for possible other attackers.
