The Comet Ping Pong Wikipedia page states that the D.C. Police department has debunked Pizzagate: ..."debunked by the Metropolitan Police Department of the District of Columbia". My question is when did they investigate this? And what if anything was found? Could this investigation have been tainted as it was performed on one of the 50 most powerful people in their district?

If you live in the D.C. you help to fund this group and I believe your questions (should you have any) warrant answers. Also in today's climate where City Police are receiving funding from the Federal Government I believe all citizens are entitled to answers. If Snopes and The NYT want to claim this is debunked that is their business. But if a government organization wants to go on record as saying definitively that no wrong doing has been done than I think we deserve answers.

We should implore the Metropolitan Police Department of the District of Columbia to demand that the Wiki be edited or demand that they tell us why they are on the record for debunking this.

Common sense would dictate that they proceed with caution. For example they could state that they have looked into the matter but do not have any evidence of wrongdoing at this time. And encouraging people to contact them if they have any evidence that is relevant. -That is a far way from saying after looking into this we find that the allegations are false...which is what 'debunking' means.
