What method is not permitted for obtaining identification data from inmates?

The method of obtaining identification data from inmates that is not permitted is through the use of physical force. This approach violates ethical standards and legal guidelines that govern law enforcement practices. Utilizing physical force undermines the dignity of the individual and can lead to significant legal repercussions, including claims of abuse and violation of civil rights.

Law enforcement and correctional officials are expected to gather information through appropriate and respectful methods, such as questioning inmates in a calm and professional manner. This promotes a safer environment for both staff and inmates and ensures that the collection of information is done in a way that is compliant with established protocols and respects inmates' rights.

Methods like handcuffing are generally used for safety during transportation or when there is a clear threat, but they do not serve as a means to extract identification data defensively or aggressively. Intimidation similarly relates to coercive techniques that are not acceptable nor effective in maintaining order or security within a detention facility. Hence, physical force stands out as a forbidden method due to its inherent risks and consequences associated with its use.
