All UK 'must be on DNA database'
The whole population and every UK visitor should be added to the national DNA database, a senior judge has said.
Lord Justice Sedley told BBC News the current England and Wales database, which holds DNA from crime suspects and scenes, was "indefensible".
He added it would be fairer to include "everybody, guilty or innocent" on it.
The Home Office said the database of four million profiles had helped solve criminal cases, but to expand it would raise logistical and ethical issues.
The DNA database - which is 12 years old - grows by 30,000 samples a month taken from suspects or recovered from crime scenes.
There has already been criticism of the database - the largest in the world - because people who are found innocent usually cannot get their details removed.
