Occams Razor, anon. Don't assume they wouldn't actually harm and kill people if it is operationally expedient.
Why sweep up Ruby Ridge and Waco? Because of the proof of a government massacre. Why sweep up 911? To cover up the… "heavy metal". Why tear down the school in Newtown? Because it was scheduled to be demolished and they needed an excuse to explain the empty school. And why tear down the School in florida? Because their narrative fell apart and they cannot allow the evidence out.
Occam's Razor.
