Answer:
On September 11, 2001 four planes were hijacked leaving the east coast. Two planes crashed into the twin towers, one at the pentagon and another in a field in Pennsylvania. The people responsible for this terrorist attack were the Al-Qaeda. After the attack the US allies supported the US in desperate time in need as the national debt increased during this time. Flights were grounded for days after the attack, airlines needed to improve security, out of this the TSA was born. The USA PATRIOT Act was passed two months after 9/11. This expanded the powers if police and was designed to prevent terrorism before it happened. Many Americans thought this was extreme and unconstitutional.
