USSR:
Outspoken community human...as : not happy with the system ...if he is clearly framed for "crime" and sent off to prison...impossible..because he is well known and respected by community ..there is plan B.
KGB watching him and pick him up due to being "drunk" or"loud"....or "sick"...The main goal for community/neighborhood to see that he got sick and went to hospital on emergency vehicle.
The "patient" injected with smart cocktail similar to Platypus venom [link to en.wikipedia.org]
with controlled application of Allodynia
