Dear CabriniGreen,

first of all, thanks very much for your compliments.
About your questions:

1. and 2. Giacomo_Vaccari’s indications are correct.
3. we can suppose that Rizzutos were hostile specially towards DiMaria (De Maria), considered a material participant in the attack against them; but probably they also understood the crafty game of the Commissos: to see what happened without apparently compromising.
4. the Camera Di Controllo has always been under the strict control of the Locali of Siderno.

My plans are to send a new article to the editor around the first weeks of July.
I hope you will find it equally interesting.
Best regards and thanks again.
