True, but there should be safety mechanisms against abuse in such cases. So the more rights they do get - the better.

PoWs come under the protection of various international agreements, commonly known as the “Geneva Conventions” though some of them are known under other titles. In many ways, these are more restrictive than the due process provisions of the criminal law.
For example, a PoW may not be extradited to a third country. This came up during the Falklands Conflict of 1982 when British forces captured an Argentine naval officer who had been indicted in Spain for torture and human rights abuses during the “dirty war” period a few years earlier. Even though there was a valid international warrant, the British could not hand him over to the Spanish and he was released with other Argentine prisoners at the end of the conflict.
