According to @HillRat in the other thread : "Based on open sources, NSA has a fleet of about 100 vehicles at most in CONUS, so they would be more likely to fly vehicles cross-country if DIRNSA needed to use a fleet vehicle. Having said that, NSA doesn't just arbitrarily get involved in domestic law enforcement cases, even ones involving crypto, so let's wait to see if there's more evidence than a random HN post to support this allegation." Good information and an entirely fair statement. I'm hoping someone from Apple can chime in directly.
