Just the other day we had a pursuit in which two different agencies tried to use tire deflation devices to stop the fleeing vehicle. While trying to deploy, we were reminded of the last time we trained on doing that...never! I started looking into the online deployment instructions the manufacturer provides and found that we have not been following those instructions at all, which can not only make our efforts to stop the fleeing vehicle less effective, but could possibly get an officer injured or even killed. I know when I start my shift tomorrow I’m going to be doing a little training on deployment.
