This would be just one of many government run DNA databases around the world, ones proposed for a variety of well meaning reasons, like healthcare and preventing crimes. But many people are worried that this “precision medicine” is the ultimate example of Big Brother and another step in ending privacy for good. So, are DNA databases worth it? The first DNA database was started in the UK in 1995. Soon, other countries followed suit. A 2008 Interpol study of 149 countries found that 54 nations had a national DNA database and 26 others planned to start one. For the most part these databases started as a way to track and catch criminals. And it’s worked. Using its own DNA database, the US’s FBI has helped solve innumerable crimes. These cases have even exonerated innocent people who were facing execution. And Chinese police have also set up a DNA database that has connected over 2,000 kidnapped children with their parents. But, the effectiveness of using DNA is not what people are concerned about. It’s how large these databases are growing. Originally, DNA was only collected from people who were convicted of crimes. However now, in countries like the United States, DNA samples are taken from people even if they are simply suspected of or questioned about a crime. This has grown the FBI database into the largest in the world, with more than 3.5% of the country’s DNA on file. If Obama’s new DNA program is deemed a success then it’s not unthinkable that one day most of the population’s DNA will be filed by the government. Advocates of the scheme suggest that the general population shouldn’t be fearful of the new proposal as the database would only be utilized to support healthcare initiatives and catch criminals. But while this could mean crimes are easier to solve, experts worry that mismanagement of such a system could leave the database open to hackers. And others sceptics are concerned that supporting the new program is one step closer to mandatory DNA samples for every man, woman and child in the country. What do you think about DNA databases? Should all countries adopt them? Let us know in the comments below, and make sure to Subscribe to get all the latest TestTube videos!
