Common Sense Note
Parents need to know that this classic courtroom drama deals with murder in almost every episode. While bodies generally aren't seen, there are images of bloody murder weapons (though in black and white, the blood is hard to discern) and detailed discussions of the less-gory elements of the crime. Some scenes -- such as a woman being chased by a man who's trying to sexually assault her -- can be mildly alarming. The now-classic chalk or tape body outline at the crime scene is a common sight. The show was made in the '50s and '60s, so there's some casual smoking and gentle reinforcement of some old-fashioned gender and racial stereotypes.
Some embraces and mild kisses.
Every episode involves a murder and the investigation of the crime, but it's not very graphic -- particularly by today's primetime standards. Bloody murder weapons are sometimes shown, but generally not bodies. Other violence depends on the episode but can include attempted sexual assault, sexual harrassment, fistfights, and the occasional threat with a gun.
While all sorts of unsavory characters appear in each episode, Mason and his crew are honorable and ethical. Given the show's "vintage" nature, expect some fairly mild gender and racial stereotypes.
Drugs / Tobacco /
Some main characters smoke (not unexpectedly, given the '50s setting). Occasional drinking.
