Got DNA? That's the question of the day out in Truro, where state
police have been loitering outside Highland Creamery, the Filling
Station and Dutra's Market, trying to score DNA samples from the local
lads. The requests were made in an attempt to solve the Christa
Worthington murder case, which has stymied investigators for three
years. While the American Civil Liberties Union has taken
exception to the investigative methods, it hasn't stopped police from
imposing themselves upon the populace. The needle in the haystack
strategy - removing every straw until you find the one that's covering
the needle - might work if all the straws were in one stack. But the
truth is that whoever murdered Worthington might not have been living
in Truro or doesn't live there now. And since it would seem unlikely
that if the murderer were in town, he (we do know that it's a he, don't
we?) would voluntarily give incriminating evidence to investigators. In
July, Nancy Murray, director of the ACLU's Bill of Rights education
project warned of the erosion of our civil
rights in the name of national defense. The Patriot Act, she said,
gives the government "extraordinary broad powers to seize your private
records, monitor your telephone and Internet use, and secretly search
your home without telling you." Like the Patriot Act, the DNA detail on
the lower Cape is, we are told, there for our protection. There are
murderers among us and the only way to be sure that we can expose them
is to give law enforcement the tools needed to catch them, whether it
be monitoring your personal correspondence or running a cotton swab
inside your mouth. [more]
The investigative value of mass DNA testing is
debatable. According to a study conducted by the University of
Nebraska, mass DNA testing is "extremely unproductive." The study,
which looked at 18 cases where mass testing was done, determined that
in only one case did it result in the crime being solved. In that case,
only 25 samples were collected. It's been suggested that the real
purpose behind the DNA harvest is to find out who doesn't want to
provide the state with a sample.
