police are definitely corporate entities in this world, with the Douman Zaibatsu controlling New Gate City's police force, specifically. you'd be right in assuming there's no marshals in this system, at least not under that title or how we'd officially know them. the company would be more willing to just hire bounty hunters for that kind of work.
as far as *legal* rights to hire their own pseudo-marshals, the NSO would have... mostly none, but it doesn't strictly matter as they're a private company funded by *mysterious backers* who apparently don't answer to the Douman Zaibatsu, so unless they step on the company's toes, the NSO is allowed to do some self-policing, which would include limited weapons permits.
any actual vigilantism is supported by the NSO, but done so strictly under the table with nothing that could legally tie it to the NSO being obvious. but they totally still sponsor it.
