I agree. He claimed to have been working inside a SCIF on a regular basis. I'm sure the National Guard would have or have access to such a facility, and have the necessary clearances. But I don't see how an inactive or active-for-training guardsman could have a need to access that much information.
There are 19 year olds with TS clearances. Some jobs just require it. It can be written into an enlistment contract. National guard and reserve units of different kinds are also kind of known for having serious racism problems. Racists use it to network and meet other racists, get the training and some credibility without actually committing to active duty. That shit in active duty is not tolerated, usually cause it's actually diverse unlike a reserve unit in a place like Massachusetts.
Another problem with clearances in general is that often those eligible come from less diverse backgrounds due to parental citizenship considerations. fields that require a clearance are often less diverse because of this.
People who have some time in the military probably won't be surprised if the situation is what the media is portraying it to be. As Abraham Lincoln pointed out about the US, the biggest problems for the country will come from within.
Yeah, my question was not that he got the clearance (presumably his MOS required it, whether full-time active or not), but why he was going into a facility and getting these documents when his unit was not called into active federal duty. There wouldn't have been any need to know so he shouldn't have had access since you need both a clearance and need to know.
