Insanity Defense....Right out of Nicholson’s One Flew over the Cuckoo’s Nest.
To paraphrase Dennis Miller: He’s crazy, so put him in a clown suit and then fry him.
Never happen. The meticulous planning including booby trapping his apartment will negate insanity. He was fully cognizant of his actions.
If the little creep actually came from a Christian home he well might be familiar with this: The ruse David used when he was on the lam because King Saul had a contract out on him - 1st Samuel 21:10 - 15.
1Sa 21:10 And David arose, and fled that day for fear of Saul, and went to Achish the king of Gath.
1Sa 21:11 And the servants of Achish said unto him, Is not this David the king of the land? did they not sing one to another of him in dances, saying, Saul hath slain his thousands, and David his ten thousands?
1Sa 21:12 And David laid up these words in his heart, and was sore afraid of Achish the king of Gath.
1Sa 21:13 And he changed his behaviour before them, and feigned himself mad in their hands, and scrabbled on the doors of the gate, and let his spittle fall down upon his beard.
1Sa 21:14 Then said Achish unto his servants, Lo, ye see the man is mad: wherefore then have ye brought him to me?
