Police in the U.S. killed at least 102 unarmed black people in 2015. Of those 102 cases, only 9 resulted in officers being charged with a crime.
Under Civil Asset Forfeiture Laws, police and prosecutors can seize one's property - cars, cash, even homes - without even charging them with a crime. Items are often sold to fund agency budgets. (See Wikipidia link for states actively involved.)
In 179 fatalities involving on-duty NYPD officers since 1999, only 3 cases were indicted, with only one resulting in conviction. 86% of the victims were either Black or Hispanic.
