The slurring and withdraw from society really beginning to back up schizophrenia as a reason.
The slurring was probably an attempt to impersonate that Joker persona.
I saw Prof Stanton Samenow on TV last night and he said this guy is most likely a criminal, sadistic sociopath, not schizophrenic.
That says it for me!
Samenow works at St Elizabeth’s (where Hinkcley was sent). I have seen Dr Samenow present in person..He has written the excellant book “The Criminal Mind”. he works with these types all the time and is well versed on this.
Half the pundits on FAUX News, including one female “Judge” have already convicted him of being evil. (I agree that what he did was evil.)
