Another old person with a gun, living in a dangerous neighborhood. 80-year-old Isaac Singletary used to bring out his gun to scare off drug dealers, so when a saw a couple of low-lifes were on his lawn, he came out with it again and told them to get off his property. Except they were undercover narcotics officers so they shot him. Isaac managed to get a shot or two off in response, but the officers were able to finish him off.
