This is just pure BS BLUSTER!
If Smollett and his lawyer sues the city of Chicago, all of that evidence that was just SEALED so no one can find out why Smollett was going to be hammered for more than a dozen Felonies gets UN-sealed!
Emmanuel and the Head of the Chicago Police were livid about being blind-sided by this sudden dropping of charges and Smollett walking. They were even more pissed at his immediate declarations by Smollett of how the Chicago Police had been incompetent and had failed to prove their case. They want very much to legally / figuratively 'rip' Smollett's 'head off' and to 'defecate down his neck'. Emmanuel is even looking into the possibility of suing Smollett for the cost of the investigation into his faux hate crime!
If Smollett and his lawyer are smart, they will RUN, not walk, away from Chicago with this GIFT / miracle 'win'.
