Gaza is not an open-air prison

When people are in prison, including open prisons, they have all and any weapons confiscated from them. Despite certain materials being banned, Gaza is still extremely heavily armed. How do people in an open-air prison manage to get their hands on so many guns, missiles, bombs, and materials for tunnels? Where and how did they get the very expensive products used to attack Israel? How did they then get into Israel with all of it? Thousands of Hamas "militants", and civilians from Gaza, were able to access Israel, and no one was there to send them back to their prison. Somehow, they left the prison premises and were not apprehended.

Does the same not also apply to internment camps?

Billions of dollars are also allowed to get into this prison, every year.

Hamas, the government in this prison, refused to have the Egyptian and Israeli blockade lifted because it would have made their resistance useless, and redundant in the eyes of Gazans. Most prisoners are desperate for more freedom, but violently resisting Israel's existence is more important to Hamas.

If Gaza is an open-air prison, Israel must be a horrible prison officer. More prisons should be like Gaza.
