So you didn't read the Law Stack exchange or follow the link to
New York Consolidated Laws, Penal Law - PEN § 120.00 Assault in the third degree which states that
A person is guilty of assault in the third degree when:
1. With intent to cause physical injury to another person, he causes such injury to such person or to a third person; or
2. He recklessly causes physical injury to another person; or
3. With criminal negligence, he causes physical injury to another person by means of a deadly weapon or a dangerous instrument.
Assault in the third degree is a class A misdemeanor.
And you didn't follow up on the students who sought medical treatment to see if any of them had received a physical injury or had an asthma attack due to the chemicals in the spray.
You just waited for me to post the relevant part of the Penal Code, didn't you? And now you're going cry about a student being suspended for violating the
Columbia Code of Conduct before the investigation into his possible criminal activity has been concluded, aren't you?
