If someone tries to hit you with a stick and you punch back that isn't legally self defense
stick
A baton or truncheon is a roughly cylindrical club made of wood, rubber, plastic or metal. It is carried as a compliance tool and defensive weapon by law-enforcement officers, correctional staff, security guards and military personnel. In many cultures, they are highly symbolic of law enforcement and are rarely used with the intention to kill.
A truncheon or baton may be used in many ways as a weapon. It can be used defensively to block; offensively to strike, jab, or bludgeon; and it can aid in the application of armlocks. The usual striking or bludgeoning action is not produced by a simple and direct hit, as with an ordinary blunt object, but rather by bringing the arm down sharply while allowing the truncheon to pivot nearly freely forward and downward, so moving its tip much faster than its handle. Batons are also used for non-weapon purposes such as breaking windows to free individuals trapped in a vehicle, or turning out a suspect's pockets during a search (as a precaution against sharp objects).
Some criminals use batons as weapons because of their simple construction and easy concealment. The use or carrying of batons or improvised clubs by people other than law enforcement officers is restricted by law in many countries.
Batons are legal for sworn law enforcement and military in most countries around the world. However, the legality of civilian carry for purpose-built batons varies greatly by country, and by local jurisdictions.
Legality is determined by the laws of the individual states. Some such as Vermont or Arizona allow for legal carry in the absence of unlawful behavior or criminal intent. Others such as California have general prohibitions against the carrying of all "club" weapons by non-law enforcement. Such jurisdictions will sometimes make exceptions for persons employed as security guards or bodyguards, will provide for permits to be obtained for legal carry, or make exceptions for persons who complete an appropriate training course.
So he's suppose to let the guy with the baton hit him because it's not "self defense"
Get the forget outta here.
