Lightfoot is corrupt AF herself. One black woman investigating another = cover for Heyward.
Lightfoot played the race card over and over again as Chicongo's first liberal lesbian licker mayor, she'll do it here for Heyward also. The race card will get played again, and again, and again. One "strong" black woman getting attacked by the white dominated media (according to Lightfoot herself) is going to back another. Same song, second verse 'n all that.
Watch some videos and read some articles about this Heyward and her henchman chief or vice-chief of police. Corrupt is a nice way of putting it. Residents there said she runs the office like a mob boss.
