So Duterte is arrested, I heard about his history a few days ago when someone from Philippines made a thread about him so I did some research and how his anti drug team fought drug lords and in the war there were casualties which should not be well if he is arrested then I think the case is closed now. Because there might be no way for him to be released again.
Yes, he was arrested , and while I appreciate your research, it's premature to assume he won't be released since the case is still in the pre-trial phase. The next step would be trial, if the case qualifies. However, as we've seen with Duterte in the Philippines, despite international criticism labeling him a killer
many Filipinos still support him because they credit his leadership for economic improvement and reduced crime rates. Some might argue crime statistics actually increased (due to the volume of drug dealers killed), but perhaps this is preferable to innocent lives being lost
This is how establishments works, if there is any there, now I hope with the new government things will get more comfy.
Duterte is not an establishment, he was a former PH president.
