"When you fall into that fear by promoting it, or acting on it, or changing your life, then those people win."
Faizan Syed is executive director of the Missouri Chapter of the Council on American-Islamic Relations.
"Definitely take due diligence but I would not take it to the extreme that many people are taking it," Syed said. "There have been posts telling Muslim women they should not wear the hijab tomorrow. They're posting that people should stay indoors tomorrow and I would totally advise against that. When you fall into that fear by promoting it, or acting on it, or changing your life, then those people win."
The flyers originated in the U.K. Authorities there are trying to figure out who sent them. But here?
"Our office, along with many other offices, have been contacting local law enforcement and the FBI all across the country and there are no credible threats against the American-Muslim community," Syed said.
