Are the Feds basically following around the LCN members on a constant basis? Kinda like how the Paparazzi follows around celebrities? Constantly taking pics, etc? Basically waiting for someone to slip up, and catch them in the act of doing something they shouldn't?

If not, how do they end up breaking most cases? Is it through actual detective type work or is it just busting someone, and putting the squeeze on them to flip? The garbage thread, and the latest gambling operation has me curious on this. Sorry, I am sort of new on this and have only recently gotten interested in the mob and ends of outs of how they operate, along with the feds. Seems like a cat and mouse game.
