MK Nissim Slomiansky (Habayit Hayehudi has proposed a law in light of the revelation that the terrorist who planned the murder of Malachi Rosenfeld was one of the terrorists released in the Shalit deal in exchange for the freedom of Gilad Shalit.

Slomiansky's proposal is to pass a law that will allow Israel to rearrest all those freed in the Shalit deal and keep them in jail for double the amount of time they had originally been convicted for.

Slomiansky says hundreds of released terrorists from that deal have broken their conditions of release and have been involved in terror planning and attacks.

I think this is a bad idea. If they have broken their agreements, you don't need a new law to arrest them. Just go do so. If the purpose of the law is to double their sentences, just retry them for their new crimes that they have allegedly committed. And it should not automatically include everyone that had been released - only those involved in terror or otherwise breaking their terms of release. Those who have been good boys and girls should not be rearrested just because others have been bad.

The way it is described just seems like a populist proposal.
