To their defense: there has been a worrying trend recently where the perpetrators of thus shootings have been much better equipped. Until recently thus shootings was mostly done with 9-mm semi-automatic weapons. But for example both the batman theater shooter and Anders Behring Breivik her in Norway did use at least some bullet resisting equipment and assault rifles.

It is totally possible that the next shooter will have full tactical armor and a fully automatic assault rifle with drum magazines. When this happened first responders has to be prepared. They shouldn't have to wait on SWAT while someone is going around shooting others. (This was what happened during the Utøya attack in Norway. The police that first reposted did not have the capability to stop the perpetrator, so they was set to direct traffic instead, while they waited on the national counter-terrorism unit to come to aid them. In the meanwhile Breivik could go around executing children.)
