There are quite a few members of Congress who view the US Park Police as unnecessary.This is whyincreases in the Dept. Of Interior budget for the US Park Police are mostly denied while small increases for other US Park Service law enforcement activities in the rest of the country are accepted.
The previous US Park Police Chief, Teresa Chambers, complained about the lack of funding in writing to the then Director of The Interior Fran Mainella. Chambers was then fired by Mainella for not being a good little girl and keeping her mouth shut. This is the same Fran Mainella by the way that wholeheartedly supported the ban on legal civilian gun possession in the parks. She also stated that the parks were safe although the crime rate was rising and in some cases even armed park rangers were being attacked by criminals.
