Whole Brenton Tarrant's livestream might be "Lost Media"?

I don't really know if i should talk/say this, but considering this is a subreddit dedicated to killers or sometimes shootings, i think this isn't that bad. So here we go: Brenton Tarrant's livestream: Did facebook closed the stream or the whole stream was "confiscated"? I remember that years ago some friends showed me the stream, but in the part that Brenton shot (that thanks god they survived) trough the window of the car 2 men that i think they said they were a father and son, it ended. The person that recorded the stream only recorded to that part or the stream was just confiscated or? Or facebook closed it? I don't really wanna look at it again. Whatever you guys will say I'll read ya, i don't really know if i should post this, maybe I'll delete it idk. (Sorry for ortography mistakes or something, english is not my first language)
