if roth had contacted rocco for the hit, would'nt he ( roth )have had some idea of what rocco looked like and suspected something was up when rocco is at the airport trying to pass himself off as a reporter?
You make good points not only about Roth recognizing Rocco at the airport, but about the dogs at the compound.
To reiterate though, while one may speculate about who may have done what in the films, such speculation would be more credible if it was not a flight of fancy.
