美国三权分立。然后，联邦权和州权又有区分。说白了，就是法官一人说话管用。

白宫回复：
Thank you for your petition regarding New York Police Department Officer Peter Liang and the shooting death of Akai Gurley.
The White House has no role in the decision of a state or local prosecutor to prosecute or not prosecute a case, and so we are not in a position to address the specific request of the petition. The local entities -- in this case, the District Attorney's office and the New York Police Department -- will be the best source for information on this matter.
With that said, we also want to share some information about the work that we're doing to build safer, stronger communities across our country.
In too many parts of our country, there is a deep distrust between communities of color and the law enforcement that is obligated to serve and protect them. And events over the past few months -- in cities and communities such as Ferguson, Staten Island, Cleveland, and Baltimore -- have brought both national and international attention to this problem.
