Reasonable doubt

[Igel]

2. But then if somebody said the neighbor also had chocolate cake

and the 3 year old could have been there, perhaps he's actually innocent.

Or if the bowl had some chocolate icing left in it and that icing can't be accounted for.

Or if the other kids showed up, looked around, and asked where their friend was ... Because he *loves* chocolate cake and excused himself 20 minutes earlier to go to the bathroom. And never returned.

Or perhaps the sinks and towels are dry, so there's no good evidence that the older kids washed up.

Lots of things could create reasonable doubt.

If knowledge of something is required, show that perhaps the person didn't necessarily have knowledge. Produce other plausible explanations. Innocent until proven guilty, not "innocent until it seems likely he maybe did it."
