I don't really get your point. If someone is going to be apprehended on your soil that basically has to be by your nationals. Agents of another nation are not capable of placing or moving someone in custody they are just criminals engaged in a kidnapping unless the situation matches some extraordinary one covered in a specific treaty.

It would be fascinating if Denmark and the US have such a treaty, and if that is recent then I would wonder if that doesn't subject Denmark to penalties by other members of the EU and/or other nations in the Schengen treaty. It certainly should.
