I suppose it could be argued that online whistleblower and now wanted man Julian Assange could have got himself off the hook had he been savvy enough when it all started unfolding to gain employment at the nearest Australian embassy.
Even just as the washer boy, for that would have provided him with at least a sniff of that intriguing thing called "diplomatic immunity".
Although of course the very title points out that this long-standing political state of affairs is in place for "diplomats".
It is an odd thing which I daresay many have never really been comfortable with, given that people like police officers, members of parliament, church hierarchy and even knights of the crown carry no "you're off the hook" sway when it comes to being held accountable for breaking the law.
But a visitor from a foreign land working within the realms of his or her embassy in their host country seemingly has this ability - if they and their political chiefs determine it is right to be applied.
