Censorship on Al-Jazeera

The following clips are self explanating. Just consider that most arabs watch Al-Jazeera to see in example pictures of the Situation in Gaza that is censored on most arab tv.  However is that allowing al-jazeera censoring a politician, may it an israeli one or any other one while explaining its position on a topic? On 31th December israeli foreign minister Tzipi Livni was interviewed on Al-Jazeera about the Gaza Operation of the Israeli Army. She several times wanted to explain the Israeli position but got very clearly in conflict with the Al-Jazeera channel who interfer in her explanations with new questions. If you thought this channel is representing freedom of speech and a balanced way on the middle east this videos will show you a different point of view.
