"It became kind of a thing to disrupt one of these webcasts when they were playing," Mr Krebs said, comparing it to terrorists wanting to see their attacks on television.
Mr Krebs said local emergency responders need to improve their training because "swatting's not going away". He said the federal government has been willing to prosecute swatting cases, including people who are involved but do not make the hoax calls. In 2016, a 22-year-old New York man was sentenced to two years in federal prison over what authorities said was a conspiracy to swat or commit other crimes against dozens of victims, including celebrities.
In 2015, a Connecticut man was sentenced to a year in federal prison for making hoax threats with gamer associates.
