If you're braindead enough to just go out and buy anything a celebrity endorses, I don't feel anything but derision for you.
Most celebrities don't even have the education or critical thought to back most of their wholly incompetent opinions, so people getting tricked by AI is really a non-issue since they're dumb enough to think that what a celebrity talks about or endorses has any meaning or impact whatsoever.
It's expensive because of the means of execution (and investigation to determine qualifying fault) and we should be applying the required amount of investigation time FOR ALL CRIMES that put people behind bars, not JUST people sentenced to death.
I'd rather spend the money to insure someone actually deserves to die or be in prison rather than have questions AT ALL surrounding the potential of an innocent person being sent to prison or executed.
The amount of innocent people in prison is ludicrous and the amount of people in prison for completely asinine and incompetent laws is beyond ridiculous.
