Police Want to Collect Abandoned DNA from Everyone
by Dr. Hsien-Hsien Lei
Posted August 2, 2007 in DNA and the Law, Polls About DNA
This morning I spent a couple of hours at my local West London high road shopping and hanging out at the park with my kindergartener. Little did I know that the police could have been following my every move, collecting my fingerprints, DNA, footwear impressions, photographs, and other samples that I might have left behind on discarded drink bottles or candy wrappers. I say “could have been” because the scenario is unlikely. For now.
The UK Home Office is planning to give police the power to collect DNA samples off anything on the street without first arresting and bringing the suspect in to a police station. That means they can collect your DNA without your knowledge from any bodily samples you leave behind in public. Police in the US have been secretly collecting “abandoned” DNA from suspects for some time to convict criminals who might have never been caught otherwise.
Professor Elizabeth Joh of the University of California Law School says that police treat abandoned DNA the same as they would trash, which is searchable without a warrant. It’s your fault if you leave your DNA in a public place.
If we look at this kind of evidence as abandoned, then it really permits the police to collect DNA from anyone — not just cold case issues — from anyone at any time and really for no good reason or any reason at all.
In addition to collecting abandoned DNA, police will also be allowed to take DNA samples from people for violating minor laws, such as littering, speeding, or not using seatbelts. Yes, they’re waving that buccal brush at YOU!
The UK national DNA database is already the largest in the world with over 5% of the population registered. If these new regulations are approved, the volume of DNA samples will swell. The US is already experiencing a shortage of trained lab technicians to process a far fewer number of DNA samples. Is the UK prepared?
Do you think the police should be allowed to take DNA samples anywhere they want? Take the poll!

You know, I really want to be horrified by this. It’s a huge invasion of privacy in a way, and catalouging the general public using any method is something that I’m vaguely against.
Realisically, what the fuck ever, dude. You want my stupid cells and mytochondria? Go for it. It’s you that has to fish my chewing gum out of the garbage can.
So much profiling stuff I want to be outraged over, and am, but it’s like a distant hum instead of an immediate sense of social actavism.
1. I don’t know that technology has ever really halted in the name of individual rights and 2. I’m lazy. Which you would know if you followed my DNA this morning. It was late. Does DNA show that you’re late?
I remember one time I was talking to someone about Singapore and their strict laws. I said I didn’t really care since I wasn’t planning on breaking any of them anyway. The person was horrified at my lack of concern because even if I was still free to do what *I* wanted to do that didn’t mean I was really free. HUH?! Who was he to tell me whether I was free or not?
If there were a law passed against blogging about DNA, 99.999999 percent of the population would likely say “I don’t really care since I am not planning on blogging about DNA anyway.” They would not feel in the least deprived of a freedom however much their feeling would be mistaken. They would simply be abandoning others to their fates because they themselves had no direct self-interest. I suspect that this is what your interlocutor was getting at more or less.
If all laws and all associated procedures and punishments are inherently just, or should, as Paul the Christian Apostle claimed, be obeyed whether they are just or not, then half of your reasoning is unassailable. If data bases can be depended upon to be prefectly protected from misuse, in perpetuity, while in the hands of highly imperfect beings, such as we are, then the other half is unassailable. Inasmuch as one or the other premise fails, the data bases are potenitally a tremendously powerful tool for injustice, oppression, etc.
Ah, yes. I see what you’re saying. I do tend to think more on the positive side of things, but certainly there are always misuses and abuses!
There is no ethical reason why this should not be done- but I’d worry that police would grow this database to some massive size- then use insufficient panel of markers (SNP’s or microsatellites) to be able to distinguish between each individual, thus increasing the likelihood of false positive identification.
Even with a huge set of markers, there are likely going to be individuals with identical genotypes. Instead of acting responsibly with this type of data, police might fudge this part of their investigation, like they have been known to do with other parts.
That’s an excellent point, Matthew. Hopefully it’s possible for defense attorneys to demand a re-test. I believe police still have to offer more than just DNA evidence to convict someone in most cases. Although they can charge a DNA profile with a crime even if they don’t know who that profile belongs to!
My word, this is worse than those vague anti-terrorism laws.
All in the name of protecting the public!

“That means they can collect your DNA without your knowledge from any bodily samples you leave behind in public.”
really gives me the creeps, not the invasion of privacy, but the fact that people are moving around towns and cities leaving bodily samples in their wake. Eewww.

If you’re not planning on doing a crime, why does it matter? Anything to put away the molesters, rapists, killers. Yay DNA!
I suppose you wouldn’t mind having a 24/7 live video feed from your house to the police station then, if you’re not committing any crimes in there?
