On the run, Snowden turns to lawyers for help

After leaking information about surveillance operations, Snowden has been on the lam. And since arriving in Moscow on 23 June, he has been in legal limbo.
Russian President Vladimir Putin said he would grant Snowden asylum in Russia - so long as he agreed to stop leaking US secrets. Snowden has meanwhile requested asylum in at least 19 countries.
Snowden is now considering his options, with Venezuela as a possibility. Here are the legal experts and activists who are helping him make a decision about his next move.
