Listen KF, there's one undeniable piece of evidence that everyone in here is pretending doesn't exist.
He crossed state lines. The state lines were crossed. The lines of the state were disregarded. The line that marks the border between two states were crossed over. The state's lines shared between the state in which Kyle murdered two people and the state where he slept at night were travelled through. The markings that define which state someone is currently residing in were walked on and over.
If this doesn't convince you that he's guilty then you are not a rational individual.
