Regarding the cryptic writing found at the scene of power line sabotage in Arkansas:
"You have expected us" is a line previously employed by the hacktivist group Anonymous.
The video below is two years old, and is largely dated.
But it the final seconds, it proclaims:
Operation Blackout. Engaged. We are Anonymous. We are legion. We do not forgive. We do not forget. To the United States government: You should have expected us.
Now the question is, is what's happening in Arkansas part of a some kind of Anonymous affiliated operation, the work or copycats with similar goals, or the work saboteur(s) with other motivations who decided to false-flag with some Anonymous imagery to throw authorities off track?
