It will not be up to the experts but the jury and when they look at this booking picture, it's game over.
If the Defense calls people who know him from the school he was thrown out of or the one teacher who said he was nuts it's game over. The guy is clearly less than of sound mind.
I wish it were other wise and I'd l9ve to be wrong but chances are looking like the trail will be moved to San Diego and the jury pool might just include enough Liberal anti-death penalty folk to either save his life or judge him insane. San Diego is iffy when it comes to justice sometimes.
