People much smarter than me have probably already noted these irregularities when the story originally broke:
-2 racist homophobes are just hanging outside a Subway at 2AM.
-One of them happen to have rope with him. Who carries rope with them (to eat or otherwise)?
-2 racists/homophobes know Jussie Smollett. Before this story I've never heard of him or watched Empire. So these racists watch Empire?
-2 racists/homophobes know Jussie Smollett is gay. How would you know this unless you've researched this on some sort of homosexual database?
-They beat him up in public. Pretty dumb thing to do in a big city like Chicago, even if it is at 2AM.
Most of these things are unlikely on their own, and borderline impossible for all these these things to occur without there being some sort of connection.
