While not perfect Sweden is probably one of the most judicially sound countries on earth. I doubt that the Swedish police would intentionally falsify reports/statements to please US interests. This is just absurd.
Melzer has said he was of the same opinion until he started looking into the case.
Don't underestimate how closely tied many European countries are to the United States. Swedish security forces snatched two asylum seekers (that we know of) off the streets in Stockholm in 2001, and handed them over to the CIA. They were immediately flown to Egypt, where they were tortured. All this was done in violation of both Swedish and international law.
Melzer has said in interviews that countries like Sweden have strong legal protections, up until the point at which they consider their own security interests to be at stake. At that point, you can expect all sorts of violations of procedure and law, dirty tricks, etc.
