Questions: 1) Do you have to first inform a suspect that he can refuse to give a urine sample before his consent can be voluntarily given? 2) Is a sample considered compromised if you do not fill out the required information on the label?
Quick Answers: 1) No, informing the suspect he can refuse to give a sample is not a prerequisite to voluntary consent. It is, however, one of the factors a court will consider to determine the voluntariness of the consent. 2) No, the sample wouldn’t be compromised as long as other unique identifiers can link it to the suspect.
