The Proud Boys could be key to the Jan 6th investigation.
We know there were Proud Boys at the hotel the day before. They were guarding Roger Stone. So we know the Proud Boys were at the hotel the same time Trumps people were having their meetings.
On the 6th, a group of Proud Boys left early for the capital, an hour or two before Trumps speech. I believe they met at the Washington monument. They started the attack before the main crowd arrived. That was not an accident, that was planned. The question is, who planned it.
We know 3 or 4 Proud Boys are cooperating with the committee. If it can be proven the Proud Boys were coordinating with Trumps people at the hotel, that's a conspiracy. It would tie Trumps people with the very people who attacked the capital first.
A quote from Deep Throat (All the Presidents Men) "In a conspiracy like this, you build from the outer edges and go step by step. If you shoot to high and miss, everybody feels more secure".
