Let's forget that the people spreading this meme don't have a security clearance either, for a moment. Why would we want to bring that into the argument? But then that is the problem with the logical fallacy of appeal to an improper authority in the form of an appeal to accomplishment.
Let me put it another way by reversing the meme:
"When a person without a security clearance tells you that Hillary did break the law."
Or how about
"When a person who is not in law enforcement tells you Hillary did break the law'?
"When a person who has no law degree tells you that you should put someone in jail without trial."
You cannot hold a presumption of innocence if you chant "Lock her up" without any charges or trial.
But there is this.
Hillary has never been tried or even charged in relation to her emails. The presumption of innocence does not judge the smartness of what she has done, but the highest ranking member of law enforcement has announced that "no reasonable prosecutor" would bring charges.
If you are for law and order, then perhaps even a basic understanding of the law would be good.
