The results show that more than half of America's executions since 1976 come from only 2% of its counties. And Harris County tops the list. Los Angeles leads the U.S. in putting people on death row - but it hasn't killed as many criminals as Harris County.
Within the top 1%, 15 counties comprise 30% of nationwide executions. Harris County killed more inmates than any other county in that group. It has executed 115 people since 1976. The next-highest, Dallas County, executed just 50 people in that period.
Harris County has been sharply criticized for the way it handles
A 2011 study about race and the death penalty from the Houston Chronicle found that of the last 13 men sentenced to die in Harris County, 12 were black. The lone, white male requested a death sentence after strangling and torturing four women and girls and raping three of them.
Texas executes the most criminals of any state. More than one-third of Texas' 305 death row inmates - and half of the 121 black death row inmates - came from Harris County, according to the same study.
A more recent analysis from Raymond Paternoster, a criminologist at the University of Maryland, found the district attorney in Harris County more than three times as likely to pursue the death penalty for black criminals.

Mistakes have definitely been made in Texas' death penalty cases. The top 2% of counties for executions also constitute 52% of the death penalty reversals since 1976, according to DPIC.
