Was the Destruction of the Death Star an Inside Job?

In our modern age of American hyper-nationalism and emerging fascism, it's not popular to express certain points of view. But some brave investigators are skeptical about claims that the Rebel Alliance was responsible for the destruction of the Death Star. They have questions that must be answered:

1) Why were a handful of rebel fighters able to penetrate the defenses of a battle station that had the capability of destroying an entire planet and the defenses to ward off several fleets of battle ships?

2) Why did Grand Moff Tarkin refuse to deploy the station’s large fleet of TIE Fighters until it was too late? Was he acting on orders from somebody to not shoot down the rebel attack force? If so, who, and why?

3) Why was the rebel pilot who supposedly destroyed the Death Star reported to be on the Death Star days, maybe hours, prior to its destruction? Why was he allowed to escape, and why were several individuals dressed in Stormtrooper uniforms seen helping him?

4) Why has there not been an investigation into allegations that Darth Vader, the second-ranking member of the Imperial Government, is in fact the father of the pilot who allegedly destroyed the Death Star?

5) Why did Lord Vader decide to break all protocols and personally pilot a lightly armored TIE Fighter? Conveniently, this placed Lord Vader outside of the Death Star when it was destroyed, where he was also conveniently able to escape from a large-sized rebel fleet that had just routed the Imperial forces. Why would Lord Vader, one of the highest ranking members of the Imperial Government, suddenly decide to fly away from the Death Star in the middle of a battle? Did he know something that the rest of the Imperial Navy didn’t?
