IARDs trg is going on everywhere. It is not meant to replace ERT/SWAT trg, only augment frontline officers with the tools to deal with active shooters. Many agencies are slowly implementing IARDs, though not soon enough for some locations. It isn't the same thing as responding to a high risk warrant or hostage situation, but it is a little bit of training that will hopefully save some lives. In other words, it means giving civilian police forces some military training to deal with a violent action. Too bad you just can't force departments to require all officers/constables to take military training before giving them a badge.
