You were not exactly "passing by". According to the map, the president was in the air, so ItzGrillux was probably heading to the airport when you rammed him, which can be interpreted as attacking, so he had a right to fight back. I agree, for my taste he spent too much time fighting with you, but my taste has nothing to do with the rules. Hence, no punishment will be issued, but I'll remind him about his duties as a security.
Thanks for reporting.
