SAN JACINTO, Calif.—The Soboba Band of Luiseno Indians held a daylong meeting Monday with leaders of other California tribes on a federal law that gives local law enforcement criminal jurisdiction on tribal lands.

The 55-year-old law has been criticized by Soboba Chairman Robert Salgado Sr. since three tribal members were killed in two shootouts with Riverside County sheriff's deputies in May.

Leaders from at least a dozen Indian tribes attended the meeting, which was designed to raise awareness of the limits of the law, called Public Law 280, and review legal options.

Tension between the Soboba tribe and the county has mounted since the shootings.

Sheriff Stanley Sniff, who declined an invitation to attend the meeting, has said his deputies are being harassed when they patrol the reservation. He believes deputies have the right to patrol the reservation at will under the law.

Sniff has asked federal gaming regulators to suspend the tribe's casino license.

About 400 tribal members live on the 10,000-acre reservation near the foothills of the San Jacinto Mountains.
