...as for the most "bloody" NY hit of a mob boss...even though its not on the list...the Sal Maranzano job, by being punched, stabbed and shot to death, in broad daylight, in front of more than few witnesses in his own office.

The Anastasia and Castellano hits were more of a...as we say on the Balkans "sacekusha", meaning the traget was killed while doing something which disabled him from taking any action...like parking or getting out of the car, or taking a shave while being completely relaxed. Or in Giancans case, while cooking and also while being watched by every possible government agency at the time. Thats "ballsy".
