Yes, he shouldn't lie. But, I already outlined in another post how easy it is for a person who wants to do their duty can lay out a fact in away that is amenable to being accused as a lie...even when the interviewer doesn't think the person intentionally tried to lie (as Strzok did in this case). You intentionally oversimplify this aspect of the issue because if you dig too deeply into the details, it starts to look like you are wrong.
Further, when given the chance to use leverage against him, it got even more unfair. Instead of giving him immunity like they did with HRC aides, they prosecuted him because he is a Trump aide.
That is the country you are working towards. You want to use the power of the state to shape the political reality of this country. Frankly, that is shameful.
I would rather the laws be applied without regard to politics.
