The three most important things to look for in a training program are what some trainers call the “3Cs.” You want the training to be consistent, coordinated, and complete.
Consistent refers to consistency with current case law and modern training principles. If what you are learning is unacceptable in court and it doesn’t match the needs of your agency, then it’s useless in all but the most extreme circumstances. For example, if your agency prohibits certain control measures, you should think twice before spending a lot of time and money learning how to do them. An exception to this rule is if you are researching them so that you can persuade your administrators or civilian oversight to change their policies.
Just remember the following advice from Roy Bedard, a police use-of-force expert and the president of Rapid Rotation Baton. “Any training program that proposes to radically change the ingrained methods of operation for cops can cause dysfunction and create mental blocks under stress.” This is why it is critically important that the training you receive outside of your agency is consistent with the training you receive from your agency. This is not always possible, but you need to be aware of when the two don’t agree.
Coordinate your training to meet your department’s specific needs. Nobody knows the plays like the players. What has happened in your department will most likely happen again. Learn from your department’s history and train for that.
Remember, one of the best things about taking classes outside of your agency is that you can bring the knowledge back to your colleagues. However, the training must also be coordinated with your supervisors and departmental policy. There is little worse than having your chief yell, "You trained them to do what?" The training should also be coordinated with all of your instructors. You should not have a firearms instructor's training conflict with the training of your DT instructor and vice versa.
