Syrian Observatory for Human Rights

"The Syrian Observatory for Human Rights, an opposition group based in London, called it “one of the deadliest days since the start of the Syrian Revolution.”"  This group which is beholden to GCC and which director never misses an opportunity to send salutations to Saudi Arabia and Qatar has been discredited and should no more be cited as a credible source.  Has this organization ever listed one killing by opponents of the regime? Ever?  And in its report on Homs, I don't think it has acknowledged any sectarian killings between groups, right?
