The term 'LAW GROUP' can be broken down into two crossword solutions: SENATE (6 letters) and POSSE (5 letters). The SENATE is a legislative body in many countries, including the United States. It is composed of elected representatives who are responsible for making laws and debating important issues. A POSSE is a group of people who are organized to enforce the law, usually by a sheriff or other law enforcement officer. Both the SENATE and the POSSE are examples of law groups, which are organizations that work to uphold the law.
