General Lawson makes mealy-mouthed excuses for sexual misconduct by the people under his command. Don't believe me? Look at this.
This isn't leadership, this is a fucked-up mix of management-speak and personal pop-theory about human nature and organisational behaviour resulting in a can't-do attitude to a difficult problem because it might be hard or something. Another name for that sort of attitude is 'cowardice' and militaries used to punish it severely. Look at him: he looks scripted by spin-masters and not even angry or embarrassed!
If Mansbridge was a journalist and not a celebrity, he'd have smelled blood and gone for the jugular, asking Lawson where his theories come from and whether this meant he'd not enforce military law against sexual transgressors. WHEN Lawson stumbled, he'd have pressed him until he found himself so deep in a hole he'd be retired before the end of the week.
Compare him to the Australian Army commander's thinking. It's beyond embarrassing.
General Lawson has the power, authority, and duty to set the standard of behaviour, attitude, and discipline across the armed forces and remove people who fail to meet that standard. He has demonstrated an attitude far short of that mark that would lead to a disciplinary hearing or dismissal in any other self-respecting workplace.
Lawson should resign or be removed immediately.
