Definition - What does Vice Squad mean?
A vice squad is a police unit that is responsible for enforcing laws that have to do with vices such as prostitution, pornography, drugs and gambling (which are classified as public-order crimes).
Vice squad members receive training that is specific to the responsibilities that they must uphold. Laws regarding vices can vary widely from state to state.
Justipedia explains Vice Squad
Although prostitution and gambling are legal in some parts of the United States, they are illegal in many other parts.
Vice officers are tasked with trying to stop public-order crimes from happening, and arresting people who participate in them. People who are found guilty of committing such crimes are subject to legal consequences such as fines and jail time.
