The BBC spent 5 years making a documentary and just finished. They had no idea that the US would in its current state when they started. That doesn't free them from criticism of the content, but the timing is a coincidence.

I haven't watched the video (linked from the article) and I certainly hope the current events caused them to reflect on whether pushing for DHS to have more power is wise, but the last line in the article doesn't give me much optimism.
