A more thorough explanation: 1. if a crime is opportunistic, then that crime has been committed by someone because they have a chance to, and not because the crime was planned
2. if a person or thing is described as opportunistic then that person uses every opportunity (or one particular opportunity) to gain power, money, publicity or unfair advantages etc
Example: 1. He added: “British organised crime gangs are fluid, flexible and opportunistic”.
2. This is an issue that should be decided by individuals and market forces, not by opportunistic politicians.
