Old Friends - S4-E22
Continuity mistake: Whilst Stone is looking at the pictures of the mobsters (as he is talking to Ann Madsen), he is holding the photos quite close together. The shot changes to a wide shot of the people in the room and the space between the photos is considerably wider than before.
Executioner - S18-E9
Factual error: Yost attacks and kills an innocent man, believing him to be Dr. Horace Garrison, a physician who administered a faulty lethal injection to a condemned prisoner, reducing him to a vegetative state rather than killing him. The problem is, medical doctors never, ever participate in an execution except to certify death, a legal requirement. They do not, ever, take an active role in killing the condemned person.
Det. Lennie Briscoe: I'm trying to decide what to arrest you for - obstruction of justice, harboring a fugitive or just being a general pain in the ass.
Trivia: Both Jerry Orbach (Det. Lennie Briscoe) and S. Epatha Merkerson (Lt. Van Buren) played guest roles before joining the cast. Orbach played a lawyer in the episode "The Wages of Love" in season two, and Merkerson played the mother of a victim in "Mushrooms" in the first season.
Question: I don't remember if it was this show or another L&O, but there was an episode where a reporter was overseas at a military encampment, reporting on a war. While there, he explains the military's plans by drawing them in the sand. Shortly later, the encampment is attacked. How could the enemy figure out where the encampment was? The reporter never said where the location was at, only what the soldiers were planning.
Suggested correction: I'm not sure where you're getting your information, but medical doctors are involved in lethal injections more than just certifying death. This is why so many groups were actively trying to stop the practice of medical profession involvement. In 2007, 17 states required physician involvement, which included doctors at times having to administer the injection.

The botched execution took place in South Carolina, which absolutely forbids medical practitioners to take an active role in killing a condemned prisoner. In fact, they are considering switching executing prisoners by firing squad instead of lethal injection, at least partly to distance medical professionals from the actual procedure leading to a person's death.
