The reason this photo is up is to show how the K2 meter had a High reading in this door way when Mike Brown was trying to ask if there was anyone in the room.
The red light in this photo is off the k2 meter when there are High Magnetic fields around it.
The Green is the standard reading.
The reason the lights are in long lines is Nathan Rasnick the Photographer used long exposure setting on his DSLR camera.
That is the only time that night anyone had a High K2 meter reading at that door way.
