Interpol - What powers does it have?

I’ve been wondering about Interpol, what is its primary task and how much power does it have in different countries. Are there any countries which don’t cooperate with it at all?

AFAIK, they have no actual power – they only advise and pool information. Their website indicates they do training, too. But I don’t think they have policemen of their own.

No one is required to cooperate with them, but since they don’t have police powers, that’s not an issue.

According to their own words (http://www.interpol.int/Public/ICPO/InterpolOverview.pdf) they essentially just act as an information clearing house. They have no actual police powers and no other compulsory powers at all.

From the thread Police outside of their jurisdiction-limitations?:

I believe that “Interpol” is better interpreted as “go-between for police organizations” (which they are) than as “International Police” (which they are not).
