Jewish Terrorists rarely serve their sentences.

Moshe Zar

There si a long history of either non prosecution, short sentences, or pardons when it comes to Israelis murdering Palestinians.
https://en.wikipedia.org/wiki/Kafr_Qasim_massacre"Following public protests, eleven Border Police officers and soldiers involved in the massacre were charged with murder. On October 16, 1958, eight of them were found guilty and sentenced to prison terms. Malinki received 17 and Dahan 15 years imprisonment. The court placed great emphasis on the fundamental responsibility of Shadmi, though the latter was not a defendant. Shadmi was subsequently charged as well, but his separate court hearing (February 29, 1959) found him innocent of murder and only guilty of extending the curfew without authority. His symbolic punishment, a fine of 10 prutot, i.e. a grush (one Israeli cent), became a standard metaphor in Israeli polemic debate.[14] The fact that other local commanders realised they had to disobey Shadmi's order was cited by the court as one of the reasons for denying Dahan's claim that he had no choice. None of the officers served out the terms of their sentences.[15]
The court of appeal (April 3, 1959) reduced Malinki's sentence to 14 years and Dahan's to 10. The Chief of Staff further reduced them to 10 and 8 years, then the Israeli President Yitzhak Ben-Zvi pardoned many and reduced some sentences to 5 years each. Finally, the Committee for the Release of Prisoners ordered the remission of one third of the prison sentences, resulting in all the convicted persons being out of prison by November 1959.[16] Soon after his release, Malinki was promoted and put in charge of security for the top secret Negev Nuclear Research Center. In 1960, Dahan was placed in charge of "Arab Affairs" by the city of Ramla.[17]"
I note that Palestinian Authorities hardly have any sort of record for prosecution and effective punishment of Palestinian committing murder and terrorism against Israelis.
