Darn. That's cold, HAL.
Guess it does look that way. But it's true. No doubt we do something similar, as will every other country.
What I find really annoying is this 'right to silence'. I would do away with it tomorrow.
The cops catch some toe rag who, say, sets fire to a company.
When questioned he simply says 'no comment'. His lawyers will probably have told him to say this. So, The cops know he did it, and he is probably going down due to other circumstances that tie him to the crime.
In your country he could, I believe, 'take the Fifth'.
He can sit there smirking or stone faced. but doesn't have to admit to anything, nor even deny it.
As his guilt is known , maybe a few minutes in a cellar with some people who don't share his sense of humour would get him to change his ways.
Roll on the day when you can simply clip a helmet onto a suspect and read his thoughts.
HAL.
