Do you think that it is morally wrong to store the DNA of innocent people on a central database?
Living in Scotland, the law says that people who have been charged of a 'violent or sexual offence' can have their DNA stored in a database for 3 years (with the possibility of extending that to 5). This isn't the DNA of people who have been convicted, but the DNA of people who have been charged and subsequently released (essentially innocent in respect to the law). In discussions with friends, I often come across the argument as follows: 'if you haven't done anything wrong, then you don't have anything to worry about'; at which point I often reply: 'if I haven't done anything wrong, then you have no need to hold my DNA'.
Do you feel that a government has a duty to hold the DNA of 'potential' criminals like this in order to benefit society at large?
