Gallagher also attracted controversies and investigations, although few formal reprimands. He was the subject in an investigation of the shooting of a young girl in Afghanistan in 2010, but was cleared of wrongdoing in it. He also allegedly tried to run over a Navy police officer with his car in 2014 after being detained at a traffic stop. By 2015, Gallagher had acquired a reputation as someone who was more interested in "fighting terrorists" and less interested in compliance with rules. In his eighth deployment in 2017, Gallagher's aggressive side was seemingly amplified, especially during the Battle for Mosul, wherein the US force mission was intended to be more advisory than direct combat. Gallagher was the subject of a number of reports from his fellow SEAL team members of actions not in keeping with the rules of war, but initially these reports were dismissed by the SEAL command structure. Only after the reports were escalated outside the SEALs were they acted upon and directed to the Naval Criminal Investigative Service (NCIS).
