[Metal Gear Solid 3: Snake Eater] Why did they let Snake keep his radio both during and after Volgin's torture?
gpt
*FAN THEORY TIME*

The Boss convinced Volgin to let Snake keep the radio during the torture on the basis of having it broadcast to Snake's support team during the torture, so as to let them *hear* every last horrible thing happening to the FOX agent (and effectively *also* be tortured by proxy).  Needless to say, Volgin not only agreed, he got a little bit hard upon hearing the Boss's torture-ception proposal because he's a murderous, sadistic freak.

As for letting Snake keep the radio *after* the torture, that was just a *major* oversight by Volgin and Johnny (which the Boss and Ocelot were more than happy to let go uncorrected).
