Under Florida Statute 784.03, the crime of misdemeanor battery is committed when a person either:
Intentionally touches or strikes another person against their will; or
Intentionally causes bodily harm to another person.
As you can see, a battery can occur from something minor, such as grabbing another person’s arm; or a battery could also occur by throwing something that strikes another person.
Importantly though, when it comes to touching or striking a person, there is no requirement that the person be injured - the non-consensual contact is sufficient.
You didn’t have to convince me, I already knew that.
