Assume a violent rape occurred in a small, rural community and that DNA evidence was collected at the scene of the crime. The victim could describe her assailant only as a young Caucasian man between 18 and 30 years of age. Assume the police then ran a local newspaper advertisement requesting that all men in the suspected category come by the station to supply saliva samples for DNA matching. Approximately 15,000 males within the suspected category were believed to reside in the nearby communities. The police intended to test all DNA samples received and to question all males in the suspected category who declined to submit samples. What issues can you identify relative to this procedure of "blanket" testing of DNA as a police procedure?
