Chpt.2 Art. 8. Prisoners of war shall be subject to the laws, regulations, and orders in force in the army of the State in whose power they are. Any act of insubordination justifies the adoption towards them of such measures of severity as may be considered necessary.
Escaped prisoners who are retaken before being able to rejoin their own army or before leaving the territory occupied by the army which captured them are liable to disciplinary punishment.
Prisoners who, after succeeding in escaping, are again taken prisoners, are not liable to any punishment on account of the previous flight.

From the 1949 Geneva Convention

Article 5

Where, in the territory of a Party to the conflict, the latter is satisfied that an individual protected person is definitely suspected of or engaged in activities hostile to the security of the State, such individual person shall not be entitled to claim such rights and privileges under the present Convention as would, if exercised in the favour of such individual person, be prejudicial to the security of such State.

Where in occupied territory an individual protected person is detained as a spy or saboteur, or as a person under definite suspicion of activity hostile to the security of the Occupying Power, such person shall, in those cases where absolute military security so requires, be regarded as having forfeited rights of communication under the present Convention.

In each case, such persons shall nevertheless be treated with humanity, and in case of trial, shall not be deprived of the rights of fair and regular trial prescribed by the present Convention. They shall also be granted the full rights and privileges of a protected person under the present Convention at the earliest date consistent with the security of the State or Occupying Power, as the case may be.

In a nutshell, U.S. military personnel don’t Mirandize detainees and FBI agents aren’t in charge of all interrogations in Afghanistan. Our troops interrogate detainees first, because battlefield intelligence is perishable. After interrogation, specific detainees may be turned over to FBI agents for additional interrogation in cases for possible prosecution.

General David Petraeus has publicly stated that U.S. troops are not Mirandizing detainees. He also said he is not concerned by the activities of FBI agents in Afghanistan.

The U.S. DoJ and the director of the FBI have clearly stated that the policy of Mirandizing specific detainees began during the previous administration. A number of terrorists have already been tried and imprisoned under this policy, including six who were involved in the 9/11 attacks.

Mr. Rogers is a minority member with time on his hands, spending taxpayer dollars and time flying to Afghanistan to criticize law enforcement personnel. As a resident of Mr. Rogers’ district, I can tell you that we here in Michigan could use a little more of his assistance and a little less of his media grandstanding.
