Criminalizing knowledge is bullshit. Why should the burden of ratting people out be placed on this dude? It is such bullshit.
Should it be illegal to tell people how to make meth? What about making alcohol? Should it have been illegal to teach people to make liquor in 1919? What about December 31st 11:59 PM 1918?
This whole thing is fucking stupid and the feds have way more interesting things to do than harass people for telling people how to cheat tests.
Its the same line of thought as suing gun manufacturers for murders or alcohol companies for drunk driving. It removes responsibility from the individual.
Not to mention this was a fucking manufactured crime. Glad every serious crime has been solved so we can bust a dude for teaching people to pass lie detector tests, which are unscientific pieces of garbage to begin with.
