And you are assuming the psychiatrist isn't honest.
I am not assuming, I strongly suspect it, or he can be a fool. Or both. There are many nut cases in US prisons and the general public is quite ignorant about mental disorders (or maybe just eager to punish and prosecute).
Human nature does not change and we know from history that in many times the majority of public ENJOYED executions, tortures etc ... (consider the public executions in the Middle Ages or Roman Circus)
Now answer my question, I gave this example: The Aliens Are Innocent!
What do you think about psychiatrist in that case?
