Or do what Amnesty International does, and send polite but urgent letters of concern to persons of authority and influence including ambassadors (UN, US etc) and to Basher Assad himself. People are likely to be better treated if the authorities know that they are the focus of international attention (conversely it totally sucks for the thousands of anonymous people being tortured today in Syrian jails).
Or cut the middle man and go directly to Amnesty. They might consider him for their letter campaign (they already have the lists of recipients and have been known to send so many letters that they can cover a jail cell).
