##Guaranteed Humane Execution
Guaranteed Humane Execution
Since anything in transit between two portals is lost when one portal loses power, you have a way to guarantee successful, painless execution, with the added bonus of body disposal. No one can argue that it's inhumane, so that problem with executing criminals is entirely eliminated.
Botched executions would amount to the portal failing before entry, which has no nasty side-effects. And a last-second stay of execution would be possible even after the executee enters the portal...just don't turn it off, execution stopped.
I mean, there'll be hippies complaining that "lost" isn't the same as "ceasing to exist" or "instant atomization". They'll have crazy theories that there's an alternate dimension or whatever where the "lost" stuff goes. But that's just crazy.
