This video attached and others made their rounds in Arab and Israeli social media. Most of the Arab comments laughed at the IDF and many of the Israelis were angry. They are both WRONG - why?
During the Jenin operation, the IDF arrested several hundreds of Arabs. Why release them?
In general, you can be 100& sure that the Shabak in the last few days has been working around the clock, interrogating the arrested.
1) Some of them were Shabak "informants" who were arrested in order to give them an "ok" by their Arab neighbors to keep from being "suspicious"
2) Some of them may be on the side of terrorists and, after talking to the Shabak, may now be new informants.
3) All of them gave up information in one way or another that was useful to the Shabak, whether they know it or not.
4) All of these people released will be look on with suspicion, no matter what they told or didn't tell the Shabak.
If the Shabak released them - you can be sure that there was a reason to do so.
