The personal security of every individual, be it physical or property security, is very important to me. That is why I would curtail the rights of every individual citizen and create a comprehensive database in which DNA and an encrypted numerical code would be stored immediately after birth. In the event of a crime, this database could be used to determine who was at the scene of the crime on the basis of items found (hair, blood.....). Even if data protectionists would be up in arms about it, such an anonymous and encrypted database would certainly be a major deterrent for potential criminals. For me personally, even a chip that everyone gets implanted would be a conceivable way of determining who was at the scene of the crime at the time. DNA samples can still be used to deny the time of the crime. Many, many crimes such as murder, assaults, burglaries and hit-and-runs could easily be solved. On the other hand, it can also be used to prove that a suspect is not guilty and convictions based on false "witness statements" or accusations could be refuted very easily. I am not a friend of surveillance, but if it serves security and is encrypted, then I am all for it.
