In October 2001, an unknown terrorist sent envelopes containing anthrax through the US Postal Service (USPS). The intended targets were news broadcasters and elected officials. One envelope was misdirected, and ended up at the State Department, where several employees were seriously injured.
17 years later, another terrorist is using the mail to attack people. Instead of anthrax, pipe bombs were sent to a cable news company, past presidents and elected officials. One package was misdelivered to the return address on the envelope – the local office of a congresswoman.
