Pretty much. There was a huge flood of “gangster” movies made in the 1930s in which every Mafia hoodlum was shown shooting up entire neighborhoods with full-auto Thompson SMGs and sniping at babies with suppressed firearms.
…only, due to the expense of the Thompson SMG, among other things, Hollywood production houses owned more of them than most nations’ armies (the US military was distinctly uninterested in the Thompson, considering it neither fish nor fowl and put off by the fact that it cost as much as four or five Springfield rifles) and they were singularly rare in criminal hands. But the confusion was helped along by lurid newsreels shown after the movie saying things like “GANGSTER ARSENAL OF TOMMY GUNS SEIZED,” and then the camera would pan for a few seconds over the captured “arsenal” showed BARs and Browning M1919s sold out the back door of the local National Guard arsenal by a corrupt supply sergeant and a small sprinkling of very ordinary hunting rifles and police service revolvers, and perhaps a double-barrel shotgun or two that had been cut down into a “lupara.”
The public, with rare exceptions, did not question any of this–which would have been difficult in an era before the Internet anyway. In, say, 1933, the only options for information were local and national newspapers and magazines of dubious accuracy and suspicious political leanings, that were more interested in lurid stories to drive sales than truth, newsreels even more lurid and politically driven, and the radio. Radio stations were owned by the same people who owned the movie production houses. All of this, plus rumor based on these things, was all anyone had to gain information about what was happening and form opinions.
I would also say that in the US it’s not so much the general public that has a problem with suppressors. There has always been a cohort of loud, opinionated Karens who don’t like the idea of private ownership of weapons of any kind at all, motivated, perhaps, by a form of Stockholm Syndrome. No, I think it’s politicians uncomfortable with the fact that the people they’re supposed to represent might take exception to the Big Plans they’ve got for us all.
