When I finished reading the story about the Molotov cocktails, I clicked on a link that was said to be posted 4 hours ago.

My French is just mediocre, and google translate wasn't the greatest. But it looks as though the story suggests that the arrest of Sollecito and Leonardo Rizzuto saved their lives because of a threat on their lives.

Hopefully my translation wasn't way off, but if that's what the story implies, my guess would be that Arcadi, Del Baso and Giardano are laying ground work for their return.
