I Disagree. Obviously technology and laws changed but to say that they had it much easy when it came to law enforcement is not true. It was more about the lack of knowledge, its easy to start convincing people when you have been collecting info on the organization for 50yrs. if it was so lax, how do you explain Luciano or Genovese going to the can. And even Capone (eventhough it was bullshit tax charge but they still got who they were supposed too) and Bonanno's legal problems in the 60s.
Then you have guys like Benny Squint and Gerry Catena who missed the problems of the 80s
