I figured if anyone was killed by this device it would cause a running mess of cascade lawsuits, even if it served as intended and killed the one who signed the TOS.
Then consider if the goggles glitched and activated on a false positive or if someone's kid tried the goggles on for a game.
This is why piracy deterrent payloads only extend to humiliation or stern warnings (rather than destruction of data or hardware). We can't restrict activations to perfectly just situations.
Something to think about as US law enforcement continues to kill Americans at four-plus a day.
