. . . but they are here for your protection. In this photo there are both civilian policemen (blue) and military border guards (green). I took this photo during a particularly tense period, so they were dressed a little more heavily than they might be on calmer days.
I particularly like the shin guards the border policeman is wearing. I have a photo of a Jordanian motorcycle cop wearing a batting helmet. Perhaps I'll dig it out and post it side by side with the Israeli border police with shin guards for a "police in baseball gear" photo exhibit.
