The mafia made so much money off that project using shoddy materials that now that someone has died and a real investigation MIGHT take place, we can expect people involved in the project to be "disappeared".
RINO Ryan, the disgraced and convicted ex-governor of Illinois, got into real trouble when a truck driver who'd bribed him, directly or indirectly, got into a fatal accident in Wisconsin that killed a whole family. Except for the eternally charmed Swimmer, a fatality often changes everything and leads to a genuine investigation with genuine accountability for the perps. Let's hope it happens here. Of course, the final consequence might be that the whole Big Dig gets shut down be foe major parts collapse, killing thousands, because of shoddy construction.
