In hindsight that would have been a better option, but hindsight is 20/20. We'd still have idiots crying she tazed someone with his hands up then. If you really think you can make something a crime because they didnt use force earlier and then had to use a higher level of force based on the suspects actions then I dont know what to say.
Edit: toned down my response and you're probably being sarcastic but i could see some actually having that train of thought.
