REUTERS: The number of calls to an FBI tip line designed to head off mass shootings and other attacks surged by 70 per cent in the week after twin massacres in El Paso, Texas, and Dayton, Ohio, federal officials said on Monday.
The Federal Bureau of Investigation fielded more than 38,000 phone and online tips during the week after the shootings, up from the 22,000 tips it typically receives on a weekly basis.
The surge is evidence of an America public made jittery by a steady drumbeat of mass shootings.
"Such increases are often observed after major incidents," the FBI said in a statement. "As always, the FBI encourages the public to remain vigilant and report any and all suspicious activity to law enforcement immediately."
FBI officials said the number of tips the centre receives each week fluctuates and not all are actionable. Some tips turn into FBI investigations while others are forwarded to local authorities. The number of FBI tips also does not include the thousands of tips that state and local law enforcement agencies have received since the shootings.
