Kevin "KC" Massey filed a Freedom of Information Act (FOIA) request back in October 2016. He just received a response (FOIA Response). Though only two and a little bit of a third page, it is rather interesting. You can read the whole Response, though I will give some highlights. "xxx" indicates redactions, mostly names.
It begins with a Summary of Events, "On September 2, 2014, Cameron County Sheriff's Office (CCSO) Investigator and Task Force Officer (TFO) for the FBI Brownsville Field Office xxx called ATF SA xxx for assistance on the 'BP Militia' case." So, the government had already set up an investigation on the "BP Militia". So, well, it wasn't just a coincidence that the events of August 29, 2014 occurred as they did. (ATF=Alcohol, Tobacco, & Firearms; SA=Special Agent; BP=Border Patrol; NFA=National Firearms Act)
