Second, a line forms, sometimes lasting for hours. For example, this roving checkpoint outside AsSawiya village held travelers up for 4 hours. The reason given for installing the flying checkpoint was that settlers had threatened to attack Al-Aqsa mosque, the holiest place in the country for Muslim Palestinians. The Army wanted to prevent retaliation from Palestinians. Meanwhile settlers, the very group that gave the threats, were free to go where they pleased. This seems to be a typical strategy: punishing Palestinians for settler crimes because it is easier than confronting the settlers.
