Al-Hayat reported that Palestinian President Mahmoud Abbas and Shin Bet head Yuval Diskin met in Jordan, where Diskin promised to release large number of Palestinian prisoners, including prisoners "with blood on their hands," directly responsible for Israeli deaths.

If Corporal Gilad Shalit doesn't have palestinian blood on his hands, it is likely that, if he is released and resumes his job, he will do before long.
