At a time of fear, when the military is effectively a member of the government coalition, and the new army chief is saying things like "everyone is obligated, in an act of loyalty, to root out certain individuals", it's worth remembering the past, and hope that lessons have been learnt.
We all know about Thaksin's popular "drug war", and the October 1973 and 1976 massacres, but less is known of the horrific efforts to suppress communist suspects in the south in the early 1970's:
Policy of government to "decisively flush out"
"merely followed orders"
Arrested and most underwent "re-education"
They bore no grudges.
"Each side claimed to fight for a better ruling system"
"Danger lurked in every corner"
