I saw that.

A quick check says the Philippines still has an obligation to cooperate, and any crimes prior to withdrawal are still subject to investigation. This according to the SCOTP.

The government is still not cooperating, the courts appear to be, but it was INTERPOL that made the arrest, and the Philippine police didn't hinder. So even though he helped elect BongBong, Bong Bong appeared to not interfere with Interpol.

Maria Ressa has a good book out - How to Stand Up to a Dictator. Watching how Duterte deal with anyone who criticized him was interesting. He filed a bunch of lawsuits against Senator Trillanes and revoked his amnesty, which the Supremes later said was valid. Senator DeLima spent six years in arbitrary detention and the cases were bogus or overturned. Ressa herself faced multiple lawsuits and was convicted of cyberlibel. One Newspaper and TV channel lost its air license and the channel was shut down. Another newspaper lost its offices when the lease was gound to be faulty. So they play hardball there and it will be interesting to see what happens to Dutz.
