It would make us a civilsed society.
Most civilsed countries do (and we used to) give defendants the right to silence, to that prosecutors had to prove their case in this setting. The previous government effectively removed this right; now the fact of one's silence (or not revealing information) is an 'act' which can be used by a jury making a decision on ones's guilt. You may have noticed in police dramas that the police caution is now ridiculously long and convoluted legalise to reflect this change.
So, let's go back to civlisation where the citizen is presumed to be innocent and doesn't have to prove that innocence – the all powerful state as to prove guilt.
