If you knew a gangster in the early 70s chances are he was a pretty smart guy. If you knew one by the end if the 90s chances are he was a schmuck. Drug addled, spoiled entitled schmuck.
I "knew" a mobster in the early 70s. Corresponded with him. Nice guy. Married my "aunt." Published a book. Died while showering - fell down, knocked himself out, and the shower curtain blocked the drain, so he drowned.
R.I.P.
