Yesterday, over 1,000 Public Schools in Las Angeles were shut down because of an email that was sent to the district. 1,531 schools were walked through to make sure everything was fine over the course of 12 hours and there were police patrols assigned to all the schools to try and help get things back to normal.
The letters that were emailed to both Los Angeles and New York City might be identical in content and where they came from, and it seems as though they've narrowed it down to an IP address from Frankfurt, Germany. Thankfully, it doesn't seem as though there is any credible threat.
New York City's police received a similar email threat and deemed it not credible and informed the police in LA and today the schools in both cities are back in session. However, NYPD Commissioner Bill Bratton thinks the police in LA overreacted and said, "This is not a credible threat. This is not something that we’re concerned with. What we would be concerned with is overreacting to it. We’ll stay aware, we’ll stay involved. But at all costs cannot start overreacting to what will possibly be a series of copycat initiatives."
New York's mayor said the threat they received read as a hoax and that it would have been a huge disservice to close schools.
