A lot of people were skeptical because the story was just too "perfect". The story never changed, nor did the truth. The media coverage changed, the outrage, feigned and otherwise only changed when CPD announced that they were investigating Smollett. As it turned out, they were obviously investigating him from the beginning. That's why they asked for his phone, not just to see if he was talking to his manager, but to see if it was damaged. The entire story didn't pass the smell test.
A lot of people see what they want to see when these sorts of things happen. I was outraged at the first reports of both this story and the Christian School boy story. However, with the very first detailed reports, it should have been obvious, and was to most, that these were highly unlikely to have occurred in the manner reported.
Illogical emotionally driven reactions are of course not limited to progressives, and conservative media sites drum up outrage too. The problem is that now the MSM is not only engaging in that practice, they do so with political perspective. It's not enough that bad things happen, they somehow must be linked to a cause.
Maybe it's because I'm older, and I grew up in a tumultuous time , but my experience in moving from those times to the relative calm of today has been that political Munchausen is not a rare occurrence. In fact the absolutely perfect crime against one's chosen world view, with the perfect antagonist, is probably less common now than than false report if such an obscene affront.
There is a meme going around that says "A better actor would have gotten away with it". The truth is that a better writer would have done so. This obviously came from the world of fiction. The best thing he can do now is to admit it all and ask for forgiveness. Everything he or his attorneys have said in the last two days has just dug the hole deeper and made him look more like a desperate liar.
