This is what the FBI said in 2018. I don't know where you are getting your data from but it's wrong. You are also conflating two things that are unrelated: police brutality and general population crimes.
"In a 2018 reporting on hate crimes from the FBI, in the cases where the race of the perpetrator was known, whites were more than twice as likely to have committed them.
Of the 6,266 known offenders:
53.6% were White
24.0% were Black or African American
12.9% race unknown
Another way that the statistic about black-on-white violence doesn’t show the whole picture is that although more than twice as many black-on-white homicides occurred compared with white-on-black homicides in the year that was measured, “white-on-black killings spiked by 22.5 percent between 2014 and 2015 after years of mostly trending downward. Killings of whites by African Americans increased by 12.2 percent, while black-on-black and white-on-white killings increased only slightly — by just 7.9 percent and 3.5 percent, respectively — between 2014 and 2015, after mostly falling since 2008.”
Violent crime has been on the decline since colonial times and is way down from the 1990s. On the other hand, police brutality (against blacks, in particular) is not down and is well documented by independent researchers.
"Research also indicates that there is extensive racial and ethnic discrimination by police and the judicial system. A substantial academic literature has compared police searches (showing that contraband is found at higher rates in whites who are stopped), bail decisions (showing that whites with the same bail decision as blacks commit more pre-trial violations), and sentencing (showing that blacks are more harshly sentenced by juries and judges than whites when the underlying facts and circumstances of the cases are similar), providing valid causal inferences of racial discrimination. Studies have documented patterns of racial discrimination, as well as patterns of police brutality and disregard for the constitutional rights of African-Americans, by police departments in various American cities, including Los Angeles, New York, Chicago and Philadelphia."
That's why there were protests worldwide after the killing of George Floyd. People everywhere are sick and tired of police brutality. When you try to quell protests against police brutality with even more vicious police brutality, you're going to simply stoke the flames. This too has been widely studied and affirmed as the exact wrong way to deal with protesters but when you are deeply attached to a "might makes right" paradigm, it's hard to give it up, I guess.
Why So Many Police Are Handling the Protests Wrong
MINNEAPOLIS - Last Wednesday, Marcell Harris was hit by a rubber bullet. He had joined the second day of protests in…
"Researchers have spent 50 years studying the way crowds of protesters and crowds of police behave—and what happens when the two interact. One thing they will tell you is that when the police respond by escalating force—wearing riot gear from the start, or using tear gas on protesters—it doesn’t work."
Then there’s this as well:
