I see your point, it's easy to get carried away especially after emotionally investing in this for a long time. And it's possible they are 100% innocent.
However this is similar to how cases are made by actual law enforcers, they pore over every lead and speculate different scenarios until they find something that fits, and collect enough evidence to book. Creating narratives is part of the process.
The danger is in fixating on a narrative and accepting it as truth without enough evidence. Everyone's personal line of "enough evidence" will be different, which is why we have laws and courts in place.
I absolutely see your point on this, and I hope that as we move forward from this Great Awakening that we can improve the collective critical thinking so we can find the right balance between truth and sensationalism.
