Statement: Two morning walkers were killed by unidentified miscreants near the joggers’ park.\nCourses of Action:\nI. Deploy police personnel around the park during early morning hours.\nII. Advise residents to walk in groups for added safety.

Introduction / Context:
Targeted attacks in public spaces demand both enforcement and community risk-reduction. Deterrence plus collective vigilance lowers repeat risk.

Given Data / Assumptions:

• Crimes occurred in early hours with low footfall.
• Police presence deters offenders and improves response time.
• Walking in groups reduces vulnerability of isolated individuals.

Concept / Approach:
I provides immediate deterrence and rapid response capability. II is a situational awareness measure for citizens until the threat profile normalises.

Step-by-Step Solution:
1) Increase patrols/CCTV near park entries/routes; improve lighting.2) Community advisories: walk in groups, carry phones/whistles, report suspicious activity.3) Investigate to identify perpetrators; adjust deployment based on intel.

Verification / Alternative check:
Combined measures are standard until apprehensions are made.

Why Other Options Are Wrong:
Only I/Only II/Either individually is weaker; Neither disregards escalating risk.

Common Pitfalls:
Short-lived deployments; neglecting lighting/CCTV.

Final Answer:
Both I and II follow.
