The U.S. government must spend more money on public safety and criminal justice within tribal communities if it wants to combat the grossly disproportionate violence there. That’s according to an advisory committee created to combat the problems.

The recommendation was just one of the suggestions made to the U.S. government and Congress by the Not Invisible Act Commission. It’s a commission composed of law enforcement, tribal leaders and the families of missing and murdered tribal members.

Issued Wednesday, the commission’s report states that there’s a billion dollar shortfall in tribal courts, another billion in law enforcement and a quarter of a billion dollar shortfall in detention services. 

The nearly 200 page report also noted a shortage of culturally relevant care for children exposed to violence, and called for more funding to tribes for DNA collection.
