Some crime scenes feature partial nudity, but nothing overtly explicit.

Main characters share passionate kissing

There are several main characters whom are single adults. Lots of references to one-night-stands and sexual relationships. There is rarely onscreen sexual content, but if ever, it is limited to kissing.

Sex crimes are a recurring theme in the series (ie: rape, sex trafficking, etc.). Sometimes details of the crimes can be graphic in nature, but are plot-relevant discussions of criminal behavior.

Almost every episode contains some sort of violent content. Shootings, stabbings and beatings, accompanied by varying amounts of injury detail. Strong blood and gore is frequently depicted at crime scenes.

Sometimes crimes are particularly disturbing regarding violence against women and children, sexual assault, torture, and crimes involving serial killers.

Frequent mild profanity such as "hell," "damn," "ass," "crap," etc. Stronger profanity includes infrequent uses of insults such as "bitch," "bastard," or "prick." The abbreviation "BS" is said somewhat often.

Later seasons have some stronger profanity than previous. Religious profanity is infrequently used such as "Jesus"/"Jesus Christ" or "goddamn."

Outliers, there's one use of "asshole" in Season 4 (Episode 9) and one use of "pussy" in Season 7 (Episode 13).

Drugs are discussed in the context of criminal cases.

Characters drink socially.

The select episodes in seasons two and three with Gregory Yates are especially intense and dark.

Each episode features very intense scenes of characters thrust into perilous situations.

Police brutality by the series main character is often shown yielding positive results.
