Fair enough, but this were actually the reason, simply adding a statement such as “if a non-EU member state wants to request data about an EU national and said data cannot be released to the law enforcement of the non-EU member without a MLAT being served to the EU national’s government” would have been enough. However, I don’t see that, and many Europeans do give “dominance of Americans” as the reason, so I simply go by the information available to me.
