The Problem with Den Tarragon are Jenny's Eggs.

Who Has to Prove It?
Let’s imagine Den says, “Matt stole Jenny’s eggs!”
Now, that’s a big thing to say. If it’s true, it means someone has done something wrong — stealing. But before anyone gets into trouble, we need to know for sure what really happened. And that’s where the law comes in.
In law, there’s a very important rule called “innocent until proven guilty.” That means everyone starts off innocent — just like an empty basket. If someone says you did something bad, they can’t just say it and make it true. They have to prove it with real evidence.
So, in this case, Den is the one making the claim, so Den has to prove it. He might try to show a video of you taking the eggs, or bring a witness who saw it happen, or show that the eggs are now in your kitchen. Only if he can bring real proof like that would people start to believe his claim.
But if Den just says, “You did it!” and has no proof — then that’s not enough. You don’t have to prove that you didn’t do it. After all, how could anyone prove something didn’t happen? You could spend forever trying to prove you didn’t steal eggs, didn’t break a window, didn’t take a biscuit — and it would never end!
That’s why the law puts the job on the person who makes the accusation. If you say someone did something wrong, you must show the evidence.
Otherwise, anyone could accuse anyone of anything, and that would be unfair.
So, in the real world — if Den accuses you of stealing Jenny’s eggs — the law says:
“Alright, Den. You’re the one saying it happened. Now show us your proof.”
Until he does, you stay innocent.
That’s how the Law works.
