(The FBI are the ones who came in when Intelligentry was closed down.)
Leonardo / IH is not very analogous to Intelligentry, which had not a single professor of science (that I'm aware of) confirming their claims. Rossi has had many highly regarded scientists test his technology and report their positive results publicly. This is a contract dispute. While I could always be wrong, I think it is highly unlikely that law enforcement will get involved, whether it be the police or the FBI. This isn't a clear cut case of criminal fraud as Intelligentry obviously was to any breathing and thinking human being.
