The city of Truro, Massachusetts is trying to collect DNA from all 790 residents to solve a crime, reports the New York Times. Its not clear why they believe that residents are more likely to be the criminal than non-residents, and it is clear that they don’t get the 4th amendment, against dragnet searches, or the 5th, against self-incrimination:
Sgt. David Perry of the Truro Police Department and other law enforcement authorities here say that the program is voluntary but that they will pay close attention to those who refuse to provide DNA.
There are numerous crimes which could be solved by door-to-door searches. We don’t allow them, and we shouldn’t allow this, either.
