A "law-abiding citizen" is someone who follows the law and respects rules in daily life. They avoid crime, meet civic duties like paying taxes, and act responsibly in their community.
I've been a law-abiding citizen ever since I grew up in the Bronx, New York. Wesley Snipes
The more sinful and guilty a person tends to feel, the less chance there is that he will be a happy, healthy, or law-abiding citizen. He will become a compulsive wrong-doer. Albert Ellis
