I too was surprised that two professionals would be sucked into a minor fracas over a few more G and Ts. Surely their training would include avoidance of minor disturbances on board that may be staged to identify Sky Marshals, On board security or enthusiastic ABPs. Having identified the aforementioned person off ill intent could quickly subdue them leave no or reduced security for more serious issues. So maybe not well trained or not that professional !!
Its a bit disturbing too that paperwork "appeared" that allowed the Marshals to depart a country in contravention of Court direction. They were charged with assault, surely not a charge worth being spirited out of a country a creating a diplomatic incident over. Seems a bit of an over reaction...................Or a well oiled machine springing into action to recover these agents as per SOPs of the TSA.
Well I suppose Mrs Brazilian Judge will have a peek over her shoulder before her next grab at a trolly full of Grog.
