30 minutes for the cops to respond.
This is why I tell people don’t bother going to Chicago anymore.
The delay in police response is a common thread in the “flash mob” epidemic. They just don’t want to confront the problem any more than the media wants to recognize it. If they had made arrests they would have to answer for claims of brutality and maybe start a bigger riot. Better to have the merchant take all the risks and loss. He’s a bloody capitalist anyhow.
