Here's what happens when you release terrorists....

The deal for Gilad Shalit will lead to many more deaths...

While there are no official statistics regarding how many freed prisoners engage in terrorism, a report published last year by The Jerusalem Center for Public Affairs reported that out of the more than 10,000 Palestinian prisoners released by Israel since 1985, over 50 percent have returned to the path of terror.

"In the terror acts committed by these freed terrorists, hundreds of Israelis were murdered, and thousands were wounded," the report said.

One example was the suicide attack in Cafe Hillel in the capital's German Colony neighborhood in 2003, in which seven people were killed including Dr. David Applebaum, head of Emergency Medicine at Shaare Zedek Medical Center, and his daughter Nava, who was to have been married the next day.

The bomber, Ramez Sali Abu Salim, from a village near Ramallah, had been released from an Israeli prison seven months earlier. He was sent by the Hamas command in Ramallah to perpetrate the attack.

Another example is Matsab Hashalmon, who was released in the Tannenbaum deal with Hizbullah in 2004. Following his release he recruited two terrorists to blow up a bus in Beersheba, killing 16 people.

According to the JCPA report, which quoted information provided by Tzahi Hanegbi, chairman of the Knesset Foreign Affairs and Defense Committee, those freed in the Tannenbaum deal have since been responsible for the murder of at least of 35 Israelis.
