Rabbi Charlie Cytron-Walker, of Congregation Beth Israel, says his desperate act to confront the gunman who held four hostages was strongly influenced by the training he received from Secure Community Network.It is the same training given to members of Tree of Life starting one year before a gunman entered their synagogue and killed 11 people in 2018.Brad Orsini conducted training at Tree of Life, as part of Secure Community Network's expansive training for synagogues across the country, due to threats directed at Jewish gatherings."Since Pittsburgh, Poway, Jersey City, Muncy, four different attacks in a 14-month period, where we lost members of our community by violent extremism," Orsini said.Orsini says Secure Community Network teaches Jewish groups how to think and respond in that critical three to five-minute span when a violent attacker presents an imminent danger."Educate a community on how to survive an attack, for example, in those three to five minutes before law enforcement getting there," Orsini said.Orsini says Cytron-Walker used one of the training methods that focus on countering the violent attack by running, hiding or fighting back; the latter is composed of two options."You can use that to fight back in two ways: hands-on control or a distraction technique," Orsini said. "He used that chair to throw at the suspect as a distraction while he was then able to escape."Orsini says more synagogues are requesting the formal security training each year.He says in 2017, Secure Community Network assigned 19 security directors to synagogues across the country.Today that number has swelled to 60.
