Traffic Enforcement Context:
High-speed pursuits pose risks to public safety.
Police needed guidelines on enforcement measures to reduce accidents and fatalities.
Judgment:
The U.S. Supreme Court held that using deadly force against a fleeing suspect who poses no immediate threat to life violates the Fourth Amendment.

Background:
Bannister challenged the imposition of traffic penalties for speeding, claiming procedural irregularities in enforcement cameras.
Key Issue:
Whether automated traffic enforcement methods (speed cameras) meet legal standards for evidence and due process.
Judgment:
The court upheld the use of speed cameras as valid enforcement tools, provided proper calibration and procedural safeguards were maintained.
Effectiveness Implications:
Automated traffic enforcement increases compliance and reduces accidents.
Reinforced public trust in traffic enforcement methods when transparency and accountability are ensured.
