Indeed and that is the problem. Andre has made a claim, that he was present at a place and time in which many other people were present. This is a believable claim given our knowledge of Andre; he lives in that part of the world, is interested in politics and so forth.

Now you arrive with the charge that Andre was not, in fact, present. Well, [i]semper necessitas probandi incumbit ei qui agit[/i]. You have laid the charge, now you must provide evidence.
