>Without any judicial order,
the administration now seeks to stop me exercising a
basic right. A right that belongs to everybody.
This is British writing style. Brits leave off the preposition "from" in these types of sentences; Americans put it in.
American English: "Administration now seeks to stop me from exercising a basic right."
British English: "Administration now seeks to stop me exercising a basic right."
I'm not a linguistics or grammar expert so I can't name the proper terms for all this. I've just observed in the past that this is a "Britishism" that differs from American style. It's interesting to see it here. Snowden wouldn't write like that. IMO, he needs to ditch Wikileaks because they've done nothing but harm him and seem to only be interested in advancing their agenda.
