Suppressing Brenton Tarrant's manifesto, no matter how bigoted, won't help understand how he became so violent or prevent others from becoming violent! Nor will it prevent other White Supremacists from reading it, since they may have been the first to save it and pass it around to each other! This will only make it harder to learn how to reduce violence, especially when the media continues to ignore research about how poverty or early child abuse lead to escalating violence!
