Re Sky News, that just illustrates that it is more important to be first than it is to be accurate. That applies everywhere - Sky News is not unusual - the U.S. is notorious for riding off in all directions before someone else does and Canada's three newspapers are not a lot better.
Actually, it's turning into a good thing because people wanting to know about events just do their own research by visiting numerous sites to make up their own minds, and ignore the standard wire-news sources because they know such sources no longer put a premium on good journalism.
