The problem I have with this is that the cardinals are not allowed to communicate with the outside, and in fact are prisoners until the new pope is announced.
The Modernist masonic cardinals don't give 1 hooey about vows to God; their job is to infiltrate, conquer and control the papacy at all costs. The masons were infiltrating the church probably 100 years before the 1950s (Pope Pius IX was imprisoned in the vatican, remember?).
So this guy Scortesco is claiming that his cousins (including the President of security) violated their most sacred duty to ensure the integrity of the papal election.
The italian nobles/security team don't take the papal election vows of secrecy that Cardinals do. Secondly, these "whistleblowers" are actually defending the papacy by showing the corruption that happened during the 58 conclave. Thirdly, these non-cardinals can only do so much to ensure the integrity of the conclave. Their job is extremely focused - make sure non-cardinals don't get in/out. No one can stop a conspiracy of cardinals, working together, with a planned way of communicating to the outside. Up until that point in history, not only was such a thing unexpected but the technology didn't exist to monitor everyone at all times...especially if you didn't expect such masonic cardinals to be so bold.
It's certainly possible for anyone to do any wicked act, but this seems really hard to believe. These people were Italian nobility, people of high ideals, who had promised to defend the pope. And obviously they would have been ready to give their life for him. To say that they would betray the papacy in this manner would be like saying the Secret Service would betray the president of this country. Such a thing has never happened in the history of this country. And the noble guard are motivated not just by a natural patriotism, but by a supernatural devotion to the vicar of Christ. The thought of them allowing the conclave to be violated just doesn't seem likely.
You're assuming that ALLOWED the conclave to be violated. Not only does charity assume the contrary, but common sense tells us that the enemy they were dealing with (i.e. masons) are a highly-prepared, powerful, and uniquely sophisticated. I'm sure security did everything in their power to stop leaks, but the masons were 2-3 steps ahead of them.
It's like the Swiss Guards, whom they work with as the pope's bodyguard. The Swiss Guards are ready to die for the pope. Just read what those guys did to protect Pius IX during the masonic invasion of Rome, and try to imagine any of them allowing people to come in and threaten to murder a newly elected pope. I realize that this is a century later, but these weren't modernist clergy, they were laypeople who had been little affected by modernism.
The Swiss Guards aren't INSIDE the conclave. Those who threatened Siri WERE THE MASONIC CARDINALS THEMSELVES (the French/German Cardinals were, are still, the most modernist). The masonic cardinals threatened Siri before the conclave ended formally,
because they knew Siri would abide by the vow of silence.
On top of all of that, if this guy really had been guilty of such a disgraceful treachery, why would he have told Scortesco about such a thing? That doesn't make any sense either.
How is it treachery to expose the infiltration of the papacy?

I don't follow your logic.
