Statement: Four cases of pickpocketing were reported last evening at a renowned five-star hotel.\nCourses of Action:\nI. Instruct hotel staff to remain vigilant and report any suspicious person or activity immediately.\nII. Install additional CCTV cameras near dining and reception areas where incidents occurred.

Introduction / Context:
Multiple theft incidents in a high-footfall, premium venue demand both behavioural and technical controls. Vigilance by trained staff complements surveillance coverage to deter, detect, and support post-incident investigation.

Given Data / Assumptions:

• Incidents cluster around dining and reception areas.
• Staff are in a position to observe and intervene early.
• CCTV acts as deterrent and provides evidentiary footage.

Concept / Approach:
Adopt layered security: people (awareness, SOPs), process (reporting/escalation), and technology (CCTV). Targeted camera placement improves coverage of hotspots; staff vigilance addresses dynamic behaviours and blind spots.

Step-by-Step Solution:
1) Brief staff on modus operandi (crowding, distraction, bag slashing) and establish rapid reporting to security control.2) Conduct a quick security audit of current camera placement, retention period, and monitoring practices.3) Add cameras and adjust angles/illumination in identified hotspots; ensure signage to increase deterrence.

Verification / Alternative check:
Either measure alone is weaker: vigilance without evidence hampers prosecution; cameras without active staff response reduce prevention.

Why Other Options Are Wrong:
Only I/Only II/Either: partial measures miss layered security benefits. Neither: contradicts basic risk management.

Common Pitfalls:
Installing cameras but failing to monitor; training staff once but not reinforcing SOPs; poor retention of footage.

Final Answer:
Both I and II follow.
