Wall Street Journal: A pharmacist who fatally shot a teenage robber in Oklahoma City was found guilty Thursday of first-degree murder in a jury trial that ignited debate over the limits of self-defense. The pharmacist, 59-year-old Jerome Ersland, fired a weapon after two young men entered his pharmacy, one of them waving a gun, in May 2009. Mr. Ersland's bullet hit 16-year-old Antwun Parker in the head, Oklahoma County prosecutors alleged. Moments later, Mr. Ersland shot Mr. Parker five more times as he lay unconscious on the ground, say prosecutors who had a security surveillance video to bolster their case.
