Didn't Joe Bonannos say it was Mangano who pretended to slap Gambino? And it's probably bullshit. Bonanno was clearly jealous of Gambinos power on the commission and Gambino supporting Gaspare Degrigorio.
No he didn´t. Read Lou Para´s post above.
Bonanno told of fistcuffs between Mangano and Anastasia. But who knows...Bonanno might have been jealous of Mangano and/or Anastasia...
