As I make my way in to the library at Broad & Porter, people are running out, as I peek in I see a tiny 40 to 50 yo black woman fighting 2 cops, a male and a little female. I'm told not to enter the second set of doors so I watch, These cops could not get the upper hand on her, she was crazy kicking and punching them, after 10mins, no back up showed up!!!! at that point I was told to leave and 15 others ran out as police roll around on the floor with her. After 15 more mins., the female cop runs out and calls for a wagon, then runs to her car around the block and pulls up. The wagon never comes, the 2 cops carrie her out cuffed but still trying to kick them. I'm just thinking if this was a 6'2" 250 lb. male what would have happened???? NO BACK UP, NO WAGON? on friday afternoon???? in the 4th Dist. Don't our cops have pepper spray or tasers?
