They're Italian. Everything's a conspiracy when you're Italian.
Don't believe me? In the 1980s, there were a series of murders in the area around Florence. They were carried out by a person or persons known as "the Monster of Florence", and have never been solved. In the 2000s, Douglas Preston and Mario Spezi - an American novelist and an Italian crime reporter - decided to investigate. They came to the conclusion that the original murders were carried out by a family of Sardinian immigrants with a score to settle before the murder weapon fell into the hands of the local mafia. However, when they went to the prosecutor overseeing the case, he refused to believe them (and even had Preston deported and Spezi locked up) because he was convinced that the murders were committed to cover up satanic rituals being carried out by a sect of Freemasonry called P2 which had ties to the Italian political, social and criminal elite and were planning to stage a series of terror attacks across Italy because they were still secretly carrying out the work of Operation Gladio, the clandestine NATO stay-behind force that was created to stop socialism and communism taking hold in Italy.
