So Minister of National Security Itamar Ben Gvir agreed to not bolt the government over Netanyahu's freezing of the judicial reform in exchange for the establishment of a National Guard force that would serve under the Minister's authority, as of now Ben Gvir himself, and would function separately from the police. All I could find about this National Guard force is that it would be used to "fight crime".

I have no idea what this means. Can anyone explain? is this just like a second police force because he doesnt trust the original? Why do we need two bodies fighting crime? Which body will have authority over any given crime scene and when?
