Free Syrian Army bombers

There is no investigation of the Free Syrian Army bombers and their crimes: except in passing in the UN Human Rights report on Syria and in he recent Amnesty International report.  Yet, war crimes by Free Syrian Army are dismissed under the pretext that their war crimes are cute, unlike the war crimes of the lousy regime.  And whenever Free Syrian Army or its allies use car bombs, I notice that the bombings were preceded by blatant threats of bombings by the Free Syrian Army.  Only days prior to the two bombings in Damascus today, commander of the Free Syrian Salafite Army made threats of "qualitative" operations in the mouthpiece of Prince Salman and his sons, Ash-Sharq Al-Awsat.
