These statistics don't involve a trial or conviction. It's based entirely on the police report when the crime was reported and only includes the race of the offender when that information is known.
A minority of police shootings involve violent crime. You will also notice that nonviolent crimes are the biggest issue, with BLM most concerned about things like Eric Garner or Tamir Rice, who was twelve years old.
"Perusal of Table 4 reveals that suspects were an average age of 36, with whites somewhat older
than blacks. Thirty-nine percent of the suspects were involved in a violent crime, 17% in a property
crime, and 5% in a drug crime. Hispanics were less likely to be involved in a violent crime,
while blacks were more likely to be involved in a property crime than whites or Hispanics.
Blacks are least likely to be armed."
Per my sibling comment, laypeople often assume the UCR cannot be trustworthy because it is collected, compiled, and analyzed by policing agencies; however, it's data are supported by the national crime victimization survey, whose data comes from victims and is collected and compiled by the justice department. So your point is even stronger than you made it out to appear. :)
