Ok, so I don't usually post on these sites, just stalk, but I was rewatching POA today and I had a question. Does anyone know if there is a reason Veritaserum can't be used on people on trial? Like, imagine how differently things could have gone if someone has given Sirius some truth serum and asked him if he's guilty. Or asked Harry if he heard Peter admit it was him?
Now obviously, the story needed to go this way for the plot and all, but I was just wondering if this had every been addressed or anything?
