Answer 1

if a person took my wallet and then swallowed it, and then told me all the money is stuck in his throat, at the level of the clavicle, boy oh boy would that make me mad!! Grrr! I'd saw off his head and I'd get all my money back!

Answer 2

normal anger would not.  Psychosis, appearing as anger, could.  

Answer 3

Nothing can. Regards. UK
