Guilty by association, in Montana
Can anyone help me with case law in Montana regarding guilty by association. My brother was recently caught when his friends car got pulled over. In the car was several drug paraphernalia and marijuana under 60gm. Both occupants in the car were charged with possession. However no paraphernalia or drugs were found on my brother. Basically is there any defense to guilty by association in the state of Montana. I know of Carr v. Commonwealth, 481 S.W.2d 91 (Ky. 1972), but that is in Kentucky. Any help?
