Father Lombardi said it was not realistic to think the Vatican could ensure 100% security for the Pope and that security guards appeared to have acted as quickly as possible.
It seems that they intervened at the earliest possible moment in a situation in which zero risk cannot be achieved,” he told the Associated Press news agency.

Presidents meet and shake hands with uncleared random people all the time; the Secret Service knows how to deal with that sort of thing.
