a dangerous job

The husband of my mom's friend is a policeman and there are a lot of times when he'd be called to go attend to a dangerous situation. I know that my mom's friend always fear that something might happen to her husband during those times. She'd get all nervous whenever she'd see the bulletproof vest, the tactical gloves, guns, and the like being readied by her husband. That's also the reason why she's so proud of her husband, she just prays that no harm comes to him.
