While the original claim needs to provide evidence, in this case that pizzagate exists, I'll give you that the emails are odd. If those phrases existed prior to pizzagate then it should be investigated. That is where I have faith in the justice department. If the police claim there's nothing to it, then I'm inclined to agree with them. I assume they investigated and utilized the emails and found no evidence of a human trafficking ring.And what evidence do they say was used to debunk it?
Don't just accept statements, think for yourself.
And yes those code words were known well before then.
More evidence for you....
