That is complete bullshit as evidenced by the federal criminal sitting president.... The ONLY time I ever see this argument is to try and paint over blatant police and state injustice and tyranny.
"A federal prosecutor's job is to jail you regardless of whether it is for downloading a file from a server or for trafficking in humans, and they will come at you with the same vigor regardless of the crime."
You have to be malicious to put forward this statement in the current environment. Or you are so propagandized you think it's true? Either one is very frightening
