User blog comment:Terry Washington/Now that superheroes can testify in open court(without revealing their secret identities)-WHAT NEXT?/@comment-2188103-20171211123737

Depends who the alien in question might be, if it's someone like the Silver Surfer or the original Captain Marvel(whose attitude to humanity is pretty much benign) then it's probably OK, if it's say, the Super-Skrull(or any other Skrull for that matter!) or even Gladiator and his fellow members of the Imperial Guard of the Shi'ar Empire never mind Galactus, then I'd say watch out!
