The sheriff’s deputies arrived at the home in San Antonio on a call that a woman had been injured in a domestic dispute. A bystander started recording a video as they pursued a shirtless man armed with a knife outside the home. Though taken from a distance, the video seemed to show the 41-year-old man, Gilbert Flores, raising his arms as the deputies opened fire, killing him.

The video appeared on television, and local officials opened an investigation. But the case, which took place last year, has drawn limited national attention — a stark contrast with the fatal police shootings of black men in recent days in Louisiana and Minnesota, which have ignited protests and calls for reform around the country.

To some Latino advocates, it is just one example of how the killings of Latinos in encounters with the police do not generate the same level of scrutiny, outrage or discourse as the fatal shootings of blacks.

“Why isn’t the community aggressively championing the victims of these crimes?” said Juan Cartagena, the president of LatinoJustice, a legal advocacy group, who sees parallels in the strained relationship many African-Americans and Latinos experience with law enforcement.
