In law, the onus is on the Plaintiff/Prosecutor to prove his allegation. In other words, it is the duty of the Plaintiff to prove his case against a Defendant. And he must prove his case beyond reasonable doubt. Hence, the defendant can exercise his right to remain silent through to the end of the case.
THE 11TH LAW OF POWER:
LEARN TO KEEP PEOPLE DEPENDENT ON YOU
Make people depend on you for their happiness and prosperity and you have nothing to fear. Never teach them enough so that they can do without you. “Thus the wise prince will think of ways to keep his citizens of every sort and under every circumstances dependent on the state and on him; and then they will always be trustworthy”…Machiavelli
