It’s like people who regularly say, “Let me be honest with you”. A shorter term for them is “liars”. (Following up with assurances of honesty is a different matter. Any sharer of oddities has to do that sometimes.)
Here’s another observation, see if it rings true. When there are “ethics courses” for a particular industry or profession, that field is rife with unethical behavior. And when ethics courses are required for people in that area…unethical behavior is tolerated as long as it’s kept out of sight.
Of course, there’s also Congress. It doesn’t require ethics training from its members nor does it give a crap about blatant (Democratic) corruption.
