Police Installing Metal Detectors at Jerusalem's Gates

Police will be installing metal detectors at a number of the entrances to the Old City of Jerusalem, according to an exclusive Galei Tzahal report.

In addition, a new Arab cyber division will be opened to track Arab coordination for terror attacks on social media platforms.

What is not clear is that since there are already plenty of knives inside every kitchen in the Old City, how will this help, and why didn't the police have an Arab cyber division until now to track their online coordination?
