The people holding the signs are members of the SA - that is, members of the paramilitary wing of the Nazi Party, not state employees or members of the military. This was taken in April 1933, when Hitler had been chancellor for a little over 8 weeks, just one week after the 'Enabling Act' had been passed. What this picture shows is actually the very process of the shift from 'just a bunch of thuggish party supporters chanting slogans' (free speech) to 'the thugs who the cops won't stop are now indistinguishable from state authority' (fascism). Not sure what it has to do with 'control of the media'. The person who took the photograph was likely part of the media.
