None of us could see a taser, that's why we were unsure. Him going invisible isn't actually a thing - nobody can go invisible randomly. he actually dropped to the ground, something you can see in the video if you pause it at the right moment.
I rewatched the video a few times and saw that he did actually get tased, but it was such an unclear thing that that was why we weren't sure. It's solved now, anyways. Thanks for pointing it out!
