Yes, but I think the Europeans were likelier to go to the long gun sooner than Americans, pre-SWAT, anyhow.
This is interesting, do you consider an SMG to be a "long gun"??
I was in Germany in the later 70s, the police always patrolled in pairs, one with a 9mm pistol, the other with a 9mm SMG.
My question about SMGs was in reference to the German police carrying them, virtually everywhere.
