Why doesn't anyone from the news media bother checking the audited financial statements for Serpent River First Nation or other First Nations ?

For example, at end of the fiscal year, Serpent River First Nation had an accumulated surplus of $22,634,347 as well as cash and cash equivalent of $3,395,885 but yet they claim they are chronically underfunded.

Many First Nations claim they lack funds for clean drinking water but when I check their audited financial information including tax-free salaries, tax-free expenses, and tax-free remuneration  paid to the chief, council members, and band administration, it is clear they are not chronically underfunded but are chronically under-taxed never mind the fact that other Canadians like myself pay out of our family budget for our clean water and sewer services.
