What points? You make it sound as if he stood to profit from this when the outcome has been clearly the opposite, and he himself had predicted it to be as much. His family has been getting death threats as a result of his work, and these carry a lot more weight in Brasil then they would in some country like the US or somewhere in Europe.
He is a very credible journalist and his story was widely well-received, his methods of procuring the information aside. If you have disagreements you should state them instead of just stating that you 'have them'
Just because Mr Greenwald is facing death threats as a result of his work doesn't mean he is 100% on his interpretation of the story. Also you forgot to mention that Greenwald's husband is a congressman which means they enjoy some enhanced security. Also you need to mention that the Brazilian's Worker's Party (the largest party in Congress) has Mr Greenwald's back. He is far from being alone in Brazi, there is a broad support from the establishment. It doesn't mean that his worries about his security are overblown, my point is that he enjoys a great deal of support especially from journalists, politicians and the Brazilian last instance's judges.
Justifying the election of someone who talked about eliminate opposition, paid tribute to a torturer and appointed a nazi as minister of culture, you really show how politically polarized are the things.
