My wife and I watch a lot of Law & Order SVU. It doesn't take very long for DNA to come up in the show, it being, at least to Hollywood, a critical aspect of criminal investigations. On SVU, the detectives will sometimes resort to trickery or just follow a perp around until they discard something in a public area from which they are able to obtain a DNA sample. That's because they are not simply allowed to take it directly.
Meanwhile, in real life, Ancestry.com and some other places have been offering a service where they analyze your DNA to tell you your likely heritage/background. Companies such as Ancestry.com are starting to accumulate large databases of DNA and who they belong to. Useful information for the police. So when I came across this article I couldn't say I was very surprised, but it made me wonder, should this be allowed?
Should police be allowed to obtain a large database of DNA that includes people with no criminal records in order to aid investigations?
Here is an article on the subject:
