For the purposes of sections 195(1), 210B(2), 210D(1) and 210F(1) and (3) of this Act, the risk criteria are that the nature of, or the circumstances of the commission of, the offence of which the convicted person has been found guilty either in themselves or as part of a pattern of behaviour are such as to demonstrate that there is a likelihood that he, if at liberty, will seriously endanger the lives, or physical or psychological well-being, of members of the public at large.
