Is the US Consulate in Jerusalem Acting Illegally

A disturbing incident in Israel in which American consulate vehicles were likely trying to transport someone illegally and even tried to run over Israeli checkpoint guards. Not exactly the actions of an ally:

On November 13 ... a five-car convoy of consulate vehicles with diplomatic plates arrived at the Gilboa crossing.

According to a detailed official Israel Police description of the incident obtained exclusively by The Jerusalem Post, the drivers refused to identify themselves or open a window or door. The drivers, according to the report, purposely blocked the crossing, tried running over one of the Israeli security guards stationed there and made indecent gestures at female guards.
