** I am not a lawyer or have any legal training, but this is how I personally view the sign. Also, the example I give may be flawed, but I think it demonstrates the point well and can be applied to more accurate circumstances. **

Another example is that you committed a crime, but not the crime they are trying to charge you with.

For example,

You and a friend rob a store. You didn’t know it going into it but your friend brought a gun.

You get arrested and you both get charged with armed robbery.

You are not guilty of armed robbery since only your friend had a gun. They would have to charge you with a crime that was accurate.

Hitting someone with a car is generally seen as a crime, but what if the pedestrian was crossing the highway?

There are many acts that are considered “crimes” that you might not be guilty of considering circumstances.

Guilt means that someone did something that’s morally wrong. Everyone who isn’t a fucking Nazi would agree that punching fascists is morally laudable, yet it’s a crime you can get convicted for.

You’d then have done it without being guilty of anything.
