The Free Syrian Army spokesman on Israeli TV: between the lies of Israel and the lies of the Syrian armed groups

Of course, the Free Syrian Army denied that one of its spokesmen appeared on Israeli TV.  Of course, Israel has a long history of inventing Arab opposition personalities and host them to say nice things about Israel.  But the Free Syrian Army denial is not credible because they--like Israel--has a long record of lying.  The Free Syrian Army sometimes claims responsibility for a car bombing but then backtracks when it is revealed that a lot of civilians have died from it. So who do I believe in this case? Well, it is safe to disbelieve both sides when they both are accomplished liars and fabricators.
