Common Sense Note
Parents need to know that this character-driven crime drama is a lot lighter on language, sex, and violence than you might expect, making it a solid choice for parents and teens. There's essentially no swearing -- it's rare to even hear a "hell" or a "damn" -- and the sexual content is tamer than comparable shows. Alcohol consumption is equally scarce, and when it happens it's generally in a social setting and involves adult characters.
Some sexual innuendo (for example, the use of a phrase like "between the sheets") and kissing, but it's pretty light.
Some characters carry guns; occasional explosions, but blood is rare.
Some "gateway" words ("damn," "hell"), but they're rarely used.
The take-away is that a criminal's mind can be put to use for a good cause. Friendship and teamwork are reinforced.
Drugs / Tobacco /
Adult characters occasionally drink alcohol in social situations.
