I ' m not really sure that ' s true . In the Canadian criminal code , manslaughter is either negligence causing death , or unlawful act manslaughter you were doing something illegal that could have killed someone , and it did kill someone without you intending to kill that person . The woman in this story was charged with criminal negligence causing death , which is essentially the same thing as manslaughter . They both can carry up to life in prison . In practice , the criminal negligence causing death is usually used for automobile offenses but that ' s just because there aren ' t a lot of other ways to kill someone through criminal negligence . At least , they aren ' t very common . <| sep |> Where have there been uses of . 22 lr ? Especially a 1022 ! ?
