Should we?

DNA samples should be taken from babies and stored on a database to
help in the fight against crime, a senior police officer said yesterday.

One reasonable answer:

Shami Chakrabarti, director of human rights
organisation Liberty, said police officers should "stick to policing,
not politics" but commended Commander Johnston’s "honesty".

"It is about time we had a debate about whether we want to turn from a nation of citizens into one of suspects," she said.

"Certainly at Liberty, the answer is No."
