Well now, let’s see:
1.The citizens may legally be on public property,
2.The recruiting stations and sidewalks in front are public property.
3. Therefore, the armed citizens have a right to be where they are.
Most armed forces “career centers” (!!!) I have seen are in leased storefronts on private property. This complicates matters slightly. I support these armed citizens, and I support arming the recruiters themselves. The “right” of the citizens to be there is contingent on the property owner’s approval.
