As the various state and territory governments are bit-by-bit expanding the use of DNA databases, here are two suggestions that would increase public confidence (or make politicians think a bit more carefully a) To give public confidence in the security of the system, DNA records of all serving or recently retired MPs and MLAs should be included.
b) As Police and Emergency Services personnel are present at crime scenes, all their DNA records should be included for elimination purposes.
This would result in a greater level of security (and might deter the occasional corrupt politician or cop).
