Kraigwy: Speaking for myself, I always remember that it's far easier to talk a man into handcuffs than it is to fight him into them. I learned long ago that when I treat folks as I would like to be treated, my job goes much smoother. But we all know, there are just some people we deal with [thankfully, a small minority] that will not cooperate, no matter how polite we are to them. Every so often, an officer just has to use force, be it tazer or OC spray...either of which is far preferable to using PR-24 side-handled batons, ASP batons, or fists.
