I know what sans means, smart arse, and no, you don't explain 'why' that word was there. What the fuck does it mean? Does it mean all the band 'but' those bracketed were apprehended, or the band were left 'sans' (which is pretty fucking archaic, by the way - pretentious some might say) those bracketed. If it's the former, then that's a crap choice of word and doesn't relate to the opening of the paragraph at all - which is about Garcia getting busted. If it's the latter, then it really makes no sense whatsoever.
