It took them longer to get something there because they were not part of to consortium that received the leaks and broke the story. They found out about it the same time the public did, and do not have access to the documents.
Also personally I prefer detailed articles that are well-investigated instead of quick, unverified news shots.
The Panama leaks were, surprisingly, covered by the news tickers in buses/trams in Graz… after the sports news. In English only. I guess it's the though that counts. /s
Not too surprised, generally, by time things hit the New York Times, it's old news. They'll be all over this by this afternoon and tomorrow.
