Funny you didn't mention the TBTJ banks in your supposed fallacy - the banks that conspired with the FBI to discuss using snipers to deal with Occupy protesters ( exposed in redacted documents) Or how they bribed police to make sure that these protests were kept away from their mansions ( NYPD/ Jamie Dimon). Or how they committed the greatest fraud in US history but suffered no prosecutions ( Public TV - Frontline investigation) Or how the US Attorney General admitted he couldn't control them (Eric Holder).
Categoring their malevolent influence as ad hominem is a fallacy, indeed.
