Confirming what many had suspected when viewing the sudden and intense collapse into anrchy that occurred in Charlotte this week, Todd Walther, spokesman for the Charlotte-Mecklenburg Fraternal Order of Police told CNN's Erin Burnett:
"This is not Charlotte that's out here. These are outside entities that are coming in and causing these problems. These are not protestors, these are criminals."

"We've got the instigators that are coming in from the outside. They were coming in on buses from out of state. If you go back and look at some of the arrests that were made last night. I can about say probably 70% of those had out-of-state IDs. They're not coming from Charlotte.
