Which act established the transportation security administration (tsa) within the department of transportation to protect the nation's transportation systems and ensure freedom of movement for people and commerce?

Protect the nation's transportation systems to ensure freedom of movement for people and commerce.The Aviation and Transportation Security Act, passed by the 107th Congress and signed on November 19, 2001, established TSA.

To implement the ‘Final Solution’, the Nazis established six purpose built extermination camps on Polish soil. These were:

Chełmno (in operation December 1941-January 1945)

Bełżec (in operation March-December 1942)

Sobibór (in operation May-July 1942 and October 1942-October 1943

Treblinka (in operation July 1942-August 1943)

Majdanek (in operation September 1942-July 1944)

Auschwitz-Birkenau (in operation March 1942-January 1945)

Chełmno was the first extermination camp to be established in December 1941. Its purpose was to murder the Jews of the surrounding area and the Łódź ghetto. The facility contained three gas vans in which victims were murdered by carbon monoxide poisoning. Once dead, the vans were driven to a nearby forest and the victims were buried in mass graves.

After the Wannsee Conference of 1942, the Nazis built additional extermination camps at Bełżec, Sobibór and Treblinka. These camps were specifically built near railway lines to make transportation easier. Instead of vans, stationary gas chambers, labelled as showers, were built to murder people with carbon monoxide poisoning created using diesel engines.

A concentration camp had been established at Majdanek in 1941. In the spring of 1942, following the Wannsee Conference, the camp was adapted to become an extermination camp by the addition of gas chambers and crematoria.

Auschwitz-Birkenau was a complex, consisting of a concentration camp, a forced labour camp and an extermination camp. Eventually it had a network of more than 40 satellite camps. Following tests in September 1941, the lethal gas Zyklon B was selected as the method of murder. Auschwitz initially had one gas chamber at the Auschwitz I camp, but this was soon expanded. By 1943, four new crematoria, with gas chambers attached, had been built in Auschwitz II. Approximately 1.1 million people were murdered in the Auschwitz gas chambers.

Not everyone who arrived at the extermination camps was murdered on arrival. Some were selected for various work tasks to help the camp operations run smoothly. Jobs included sorting and processing the possessions of everyone who arrived at the camp, administrative work and heavy manual work.

The majority of those selected for any kind of work within this type of camp would die within weeks or months of their arrival from lack of food, disease or overwork. Those that survived were often killed after a short period and replaced with new arrivals.

Over the course of the Holocaust, more than three million people were killed at extermination camps.
