From Kashin’s link, there’s a wonderful and amazing section on the website supporting Bakhmina. You can check by last name who signed the appeal and who didn’t. http://bakhmina.ru/search.php I found out that Leonid Yakovlevich Gozman signed it. But Sergei Adamovich Kovalyov and Vladimir Vladimirovich Putin did not. So, yeah, they’re untouchables (tm).
