inadequate training can cost just as much as (or more than) adequate training. If a police department is requisitioning big powerful toys, they are going to play with them. Going off-roading in the desert burns just as much fuel as doing a proper training seminar.
My point was the police don't really train or else we wouldn't have all these issues with their lack of professionalism and capabilities. They might "train" on how to clear a room but they don't train on appropriate escalation of force, for example.
