"When a person, being without fault, is in a place where he has a right to be, is violently assaulted, he may, without retreating, repel by force, and if, in the reasonable exercise of his right of self defense, his assailant is killed, he is justified." Runyan v. State, 57 Ind. 80; Miller v. State, 74 Ind. 1.
"These principles apply as well to an officer attempting to make an arrest, who abuses his authority and transcends the bounds thereof by the use of unnecessary force and violence, as they do to a private individual who unlawfully uses such force and violence." Jones v. State, 26 Tex. App. I; Beaverts v. State, 4 Tex. App. 1 75; Skidmore v. State, 43 Tex. 93, 903.
"An illegal arrest is an assault and battery. The person so attempted to be restrained of his liberty has the same right to use force in defending himself as he would in repelling any other assault and battery." (State v. Robinson, 145 ME. 77, 72 ATL. 260).
