The clenched-fist salute: a show of solidarity for Marxist, Communist and other radical ideology. It is this pre-assassination concept of the clenched fist salute that must be recognized to understand LHO's use of this symbol while under arrest, and also dying on the police basement floor, in Dallas.
Oswald's right fist still clenched tightly after displaying it to Detective Combest in response to whether Oswald wanted to say anything after being mortally wounded.
Oswald lost consciousness and eventually died while still displaying the Marxist clenched fist salute. Oswald's Marxist dying declaration, his last intentional physical act on earth, was first confirmed and published in Malcontent.
