No question that everything you're mentioning is indicative of some of the more demented,twisted examples of Mob scumbags.
However, the original point of this thread is what some guys did to collect shylock loans.
None of what you mentioned had anything to do with that.

Once again, Lou and I totally agree. Let's say I was familiar with a couple of fellows that were employed by the collection division of the Pittsburgh Mothers and Fathers Italian Association. I know for a fact that physical harm to either the person in default, let alone any family member, was hardly ever a card in the deck. If and when it needed to be played then it was on the bottom. Almost all in default had fear of violence and that was enough for them to pay up. Besides, they knew that sooner or later they'd be back for another loan mostly to pay off their gambling debts. A vicious cycle for sure :-(
