If, Ninety-nine percent of the FBI agents were honest and hard-working agents and who avoid the corruption that comes from the politicization of their agency.

But when the 99% stay silent and watch as the other 1% destroys the integrity of their agency, they become no better than the corrupt minority.

Which makes 99% of them cowards who can’t be trusted because they obey orders whatever those may be and accept what is done in their name.
