Americans loooooooooooooooove pointing out at their population density as a thought-terminating cliché although it's very rarely relevant to any discussion.
The size of your continent does not influence the size of your metro areas, dipshits. LA isn't the way it is because Wyoming is empty, LA is the way it is because a bunch of dumbasses decided that local mass transit and terraced housing should be outlawed and bulldozed in order to fuck over African-Americans communities.
Except the Trials where that precedent was supposedly established actually allowed a great many people to escape conviction using that exact defense, then the prosecution subsequently gave up on the trials altogether. The Nuremberg trials were a travesty of justice, not because the Allies set up kangaroo courts, but because in an attempt to avoid such accusations and through unbelievable prosecutorial incompetence they let almost every Nazi who was still alive run free.
What I'm getting at is, don't expect justice to magically administer itself.
