"It also hasn't been released what the diameter, strength or material (wooden dowel, lead pipe, etc.) was used as the makeshift flagpoles..."
Despite confusion among news organs as to which department the agent is question is answerable to, one thing for sure is that a federal agent opened fire during physical violence at a pro-Israel rally. As reported by KNBC (of Los Angeles, Calif.) on July 14, 2014, and also by the Los Angeles Times on 13 July, 2014, gunfire erupted at a pro-Israel peace demonstration that was loudly interrupted by pro-Palestinian protesters.
Apparently in response to the current armed conflict between Israel and the Hamas terrorist organization dominated government of the Gaza Strip, and also as a counter to the pro-Palestinian march last week-end, reportedly 500 marchers favoring the Jewish State made their presence known outside of the Los Angeles Federal Building on Sunday afternoon. By all accounts, the assembled were peaceful until the closing moments of the rally when a pick-up truck filled with pro-Palestinians drove by, and according to witnesses, agitated, taunted and assaulted the Israel supporters.
Four of the pro-Palestinian riders were arrested by Los Angeles County Sheriff's deputies on charges of allegedly assaulting the pro-Israeli marchers with the wooden flagpoles they used for their Palestinian flags. When one of the riders lost his grip on his flagpole, he ended up in a scuffle when he exited his truck to retrieve it. It was then a federal law enforcement officer intervened and a shot was fired by the official. Still under investigation by the LA Sheriff's Office, one of the few facts made public is that no one was injured by the gunshot. It also hasn't been released what the diameter, strength or material (wooden dowel, lead pipe, etc.) was used as the makeshift flagpoles.
Initially reported that the federal agent was employed by the Department of Homeland Security (DHS), the NBC affiliate in Los Angeles updated that the agent in question was actually a member of the Federal Protective Service (FPS). Which of either agencies the agent is employed by is a moot point. FPS is one of the many organizations that falls under the overall control of the Department of Homeland Security.
As of the time of this publication, no official explanation has been made public why the FPS agent used his firearm during the altercation. However, it is common knowledge that if a law enforcement officer reasonably believes a suspect is using a vehicle as a deadly weapon, it's normally acceptable practice for an officer to utilize deadly force to protect himself or innocent possible victims from harm.
