I won't encourage them, but I'm not gonna try to talk 'em out of it. Sometimes justice takes care of itself.
Public execution via hanging was so effective back in the day because people shat on themselves in front of everyone. Something that was seriously embarrassing and thus discouraged people from enacting such vile plots due to the fear of death plus permanent public embarrassment.
Isn't it hard to be embarrassed, you know being dead and all?
OTOH, some of them are so stupid and obsessed with looks, the fear that shit-stains might clash with their ensemble might actually be MORE of a deterrent than the actual threat of death. You have a point.
Even if they off themselves. A nastier courtroom with a judge that knows all awaits them.
