The Korea Times has an article published about a GI behaving badly that I recommend people do not take at face value considering the frequent yellow journalism of the KT:
Seoul Suseo Police Station arrested an American soldier private first class (22) for violently harassing a taxi driver while he was driving his taxi on June 30.
The police said that the pfc, who is stationed at the Seoul Air Base, got on the taxi driven by Choi (46) at 5:10 A.M., and started beating and strangling him from behind where he was seated while the taxi was running on Cheongdam bridge.
Police, after investigating the case, found out that the taxi at the time of the accident was running with speed of faster than 100km/h.
The police also said that when Choi pulled over his taxi in Suseo-dong, Gangnam-gu, to get help, the private ditched the taxi and tried to flee the scene, and, as Choi chased after him, again threatened him with hostile action. [Korea Times]
