But in any case, I am ALREADY at least not a member of one of the mafias.
In a fit of delirium, one could assume that the mafia deliberately blocked its own member, whom it was using, in order to later clear his name, especially after an investigation by a captain who only kills other mafia members...
Of course, this is a far-fetched scenario, but if we assume that the mafia didn't shoot at all, that is also a possibility...
