That's not what happened though. He dictated where the police were capable of having a word with him, and they chose not to do so there. It's totally possible that there are legitimate reasons for that (if you already have enough evidence to convict, there would be no reason to 'interview' someone except in an arrest-friendly setting), but it's still a worthwhile distinction. This isn't someone calling up the police and going "I'll talk to you, but only if you agree to meet me at Starbucks." It's someone leveraging international law to leave the police with only one option.
