Listening to Chicago police scanner is a trip. Available online. One guy that had been car jacked waited three hours for police to show up.
Cops en route to a park where a significant violent disturbance was taking place were told to delay their arrival at the park because needed backup from other patrol units was delayed due to other calls.
while he waited he probably ahd his wallet stolen next and then when the next robbers came along, they got mad he had no money so they beat him up.
