I’m not thinking of the men so much as I’m thinking about the civil rights issues of blanket DNA testing.
I have a female relative who worked as a nurse’s aid. She abused a patient in a state-run nursing home because, due to a very bad temper, she was very unsuited for this job. Her patient was able to identify her attacker, and my relative was punished. But it’s not hard to imagine a situation where an elderly patient with dementia is abused but can’t help the police with her case. Maybe a nurse’s aid gets accidentally cut by the patient, who doesn’t understand what’s going on, and so hits her with the nearest blunt object. The nurse is wearing gloves, so no finger prints, but leaves the weapon and her blood behind. It’s pretty clear what happened from the physical evidence, and the DNA is identified as belonging to the victim and another woman, but the attacker isn’t in the system. I would feel very uncomfortable with blanket DNA screening of all the female employees of the nursing home for the same reason I’m uncomfortable with it here. Too much room for police and state misbehavior. Both acts are reprehensible and should be dealt with by narrowing down the subject pool and getting a warrant for DNA based on probable cause.
