 Rings of security or concentric circles. If you were to take a pencil on a paper and you would start drawing circles without ever lifting the pencil up and you just keep going out and out and out and out, those are concentric circles. Okay, so like an immediate circle around probably the stage and the inside area. Maybe the second circle would be like the outside where you can still kind of see, but you're outside the fences. Maybe those barn areas where the alleged shooter was on top of and then going out and out as far as like a circumference, it sounds like.
