Also, I need it explained to me how Trump firing Comey, or considering firing others, is an indication of his guilt.

If he was guilty, he would be doing everything possible to lay low, and AVOID the appearance of interference. The only way that's not the case is if he has the intelligence of a piece of toast. Anyone with an IQ of 9 would know that the optics of such a move would stir the pot, and it wouldn't end the investigation anyway.

On the other hand, if Trump is innocent, then he would know for sure that these people are engaged in a fruitless investigation. Whatever they are doing, it is not going to uncover any evidence of Russian collusion, because Trump knows for sure that he didn't collude with Russia. From Trump's point of view, whatever they are doing must be outside the scope of the investigation. Whatever they uncover must be the result of a witch hunt coordinated by the opposition. This theory is supported by the fact that anonymous sources are leaking suggestive, but ultimately meaningless, garbage in order to color the media discourse against Trump.

If you're Trump....are you just gonna let all that happen? Are you really gonna not-fire people because of lol-optics??

Trump's behavior seems to be strong evidence against the existence of Russian collusion, not the other way around. And I really can't believe that there are people in this world, and in this thread, who consider themselves intelligent, and still don't get this.
