Many of you are not very good lawyers. It's very simple to understand battery if you just read your statutes. It literally depends on what state the battery occurs in and what the state defines as a battery.
For example, in the state of Florida, there are various defenses to battery Charges:
Consent (Yes, it's a real thing)
Intent is an essential element of a battery. Therefore, if the victim consented to the touching, no criminal battery can occur. Likewise, in the right circumstances, the process of mutual combat could be raised. Under this process, if two (or more) people mutually engage in a fight, neither should be charged with battery because they both agreed to be touched or struck by the other.
So, rather than just blatantly tell someone they are wrong, one should consider all of the elements, the state in which the incident occurred, and any other extenuating factors, rather than just jump on this site and tell someone they're wrong. Otherwise, I guess that would make YOU wrong. I hope you feel a little less ignorant. Remember, ignorance is not stupidity, it's lacking the proper knowledge. Yes, that would be you.
