I’ve been to a stunning transport museum in Germany. Incredible restored vehicles from all over the world. Even a Concorde jet. Super cool.
They also have Hitler’s car there. It’s stunning, it’s historical, it happened, and the modern crime would be to hide it away, or destroy it.
Without our past, we can’t learn for our future. Put that kind of stuff in a museum. Have an information display about why it was there. Inform the future generations. Empower them with knowledge.
