Jimmy, the dept. I served on in the late 60's had a large number of WW11 and Korean War vets who had a bucket load of combat bring backs including German MP38's MP 40's as well as Thompsons ,Grease Guns, M2 Carbines as well as a Sten or 2. When the anti-war and racial riots broke out in our town, the opposition had no clue what we were armed with. In a number of cases large groups were broken up when an old grizzled Sgt. would fire a full auto burst up in the air. That would never happen today ,but in 1969 none of us got into trouble, Our LT. carried an M2 Carbine and was "the meanest *** on the street" Truly ,"the past is another country and they did things differently there".
