Bias in prisoner swap story

Mainstream outlets cover the Israeli-Palestinian prisoner swap from the Israeli perspective (i.e., "Israeli Solder to be Released") while others and foreign outlets go either way. In this case (pictured at right), only Al Jazeera takes an angle on the Palestinian prisoners.

Incidentally, the ratio of prisoners being freed (1000 Palestinians to 1 Israeli) is interesting because it lends itself to either of two diametrically opposed conclusions: (1) 1000 to 1? How many warmongering Palestinians are there?, or (2) 1000 to 1? How could the Israelis imprison so many Palestinians?
