That's doctoring the video, he cut out them talking in his office and her coming down to the lab touching his forehead and leaving.
Also, I just rewatched this scene of Heyward playing the Wanda footage and directly after he and Jimmy both say resurrecting Vision is illegal it violated section 630 something of the Sakovia Accords and Vision's living will. So there, resurrecting Vision is illegal. He broke the law, the end. lol
Yes, Jimmy, Wanda and Darcy probably should be in custody to. But isn't that common cops and robbers trope? A cop goes rogue, breaks all the rules to solve the case, once the case is solved and rogue cop is vindicated all the illegal things they did to solve the crime are forgiven. Beverly Hills Cop, Lethal Weapon, Dirty Harry etc. All did this.
