I know this is a weird question. I'm curious as to what counts as assault, in the sense a person would be likely found guilty of it in court. Generally assault is considered fighting someone who did not want to fight you. So does this mean if two people agree to a fight, it's legal? This seems to be the case with MMA where there wear virtually no safety equipment.
What if an aggressor gets up in another persons face, then would the person be able to hit first? I saw this in a youtube video: a police officer responded to a 911 call. The person who he called was a army drill sergeant and started yelling at the police officer and getting up in his face (like in movies like Full Metal Jacket). Though the drill sergeant technically didn't touch the police officer, the officer hit him in the face, pinned him and arrested him. Though there were other factors like the drill instructor seemed to be on drugs.
If a person does something minor like throws water at a person or shoves a person would that count as assault? For example in sports games you occasionally see a player or coach shove someone. If there was a prank like shoot someone with a water gun, could this be assault if they didn't agree to it?
