Years ago, I once did exhaustive research on White police officers accidentally killing Black cops.
Beginning with the first such shooting in 1940, when white officers in Harlem mistook a black officer, John A. Holt Jr., for a burglar and shot him dead in his own apartment building
After a White officer shot and killed an undercover detective William Capers in 1972, the department drew up guidelines intended to prevent fraternal fire and undercover officers began wearing their badges on strings around their necks. I remember this case because the White cop, who was distraught over what happened, was later promoted to Sargeant.
March 1973 – Black off-duty cop Irving E. Wright was gunned down and killed by White cops who mistook him for a robber
In 1992, Derwin Pannell, a Black transit officer, was shot in the neck by White cops at an L train stop in Canarsie, Brooklyn. Fortunately, he survived.
In 1994, a White cop shot Black undercover transit officer Desmond Robinson who was chasing a teenager with his gun out. Peter Del-Debbio, who is White, came from the other direction and opened fire. Del Debbio, thinking he was so righteous, fired the last few shots into Robinson’s back at close range.
Now, I knew Desmond. At one time, we lived in the same zip code. He was quite a happy- go-lucky guy. He wasn’t anymore following his recovery from nearly being killed by that trigger happy fool. Del Debbio was convicted of assault and got five years probation.
In 2000, Providence, R.I., off-duty Black police sergeant, Cornel Young Jr, was accidentally killed by two uniformed White cops while he was trying to break up a fight in a parking lot. Young, at the time the son of the department’s highest-ranking Black officer, was dressed in baggy jeans, an overcoat and a baseball cap. And he was carrying his service gun.
In 2006, a gang picked a fight with off-duty cop Eric Hernandez at a White Castle in the Bronx, N.Y., at a White Castle restaurant in the Bronx. Officer Alfredo Toro responded to a 911 call and shot Hernandez, not realizing he was a colleague. Hernandez later died.
In 2008, a Black off-duty Mount Vernon, N.Y., police officer Officer Christopher Ridley was killed by a Westchester County policeman while holding an assault suspect at gunpoint.
In 2009, 25-year-old Black New York City police officer Omar J. Edwards was shot and killed by a white officer on a Harlem street while in street clothes. He had his service weapon out and was chasing a man who had broken into his car, police said.
I stopped researching at this point in 2009. But I do recall some quite ugly incidents later on.
What I did not include (because there were many incidents of same) is the number of instances where White cops seriously assaulted, (but did not kill), Black undercover police officers.
