Statement–Argument — Should police pickets on roads be disallowed from stopping buses to check travellers’ luggage? Arguments: I. Yes. Such checks inconvenience travellers and worsen traffic congestion. II. No. Blanket disallowance would unduly curtail necessary policing powers used for safety, interdiction, and crime prevention.

Introduction / Context:
Roadside checks support interdiction of contraband, trafficking, and threats. The question proposes disallowing such checks for buses.

Given Data / Assumptions:

• Public safety sometimes requires stop-and-check operations.
• Convenience and congestion concerns are real but can be managed by protocol.
• Proportionality and legality govern police powers.

Concept / Approach:
Weigh operational necessity against inconvenience. A categorical ban undermines safety tools, whereas regulated checks can reduce friction.

Step-by-Step Solution:
1) I: Focuses on inconvenience and traffic, not on safety outcomes; these can be addressed via scheduling, lanes, and rapid protocols—weak.2) II: Highlights that an outright prohibition would disable legitimate policing—strong.

Verification / Alternative check:
Standard practice authorises checks under legal safeguards (reasonable suspicion, documentation).

Why Other Options Are Wrong:
They overstate inconvenience while ignoring core security functions.

Common Pitfalls:
Equating better procedure with prohibition.

Final Answer:
if only argument II is strong.
