The folks who installed and monitor the surveillance system at State Farm Arena are currently under subpoena to testify in federal court regarding this, so while no one has yet been arrested, it looks like evidence is being collected for presentation to a grand jury. My source for this is a long time (40+ year) friend inside the surveillance camera company with the contract. He cant much talk about it due to the subpoena so thats all I know.
Wow.. interesting to know. Thanks for sharing that.
