Common law vicarious liability for conspirator's crimes entails liability for:

• A. All crimes committed by co-conspirators in furtherance of the conspiracy
• B. Only the crimes the conspirator personally aided
• C. Crimes not in furtherance
• D. No liability for crimes committed by co-conspirators

Answer: (A)

Vicarious liability in conspiracies rests on the idea that once a plan is formed, each participant can be responsible for crimes committed by others if those crimes were in furtherance of the conspiracy and within its scope. Under this rule, a conspirator is liable for all offenses committed by fellow conspirators in furtherance of the plan, even if the conspirator did not personally commit the act or even know about it. The rationale is to prevent participants from shielding themselves by not knowing what their co-conspirators do, as long as the acts help advance the shared objective. Acts not in furtherance or outside the plan’s scope are not covered. So the correct view is that liability extends to all crimes committed by co-conspirators in furtherance of the conspiracy.
