Police's resources should be used diligently by its men

What is the purpose of police patrol cars? They enable mobility of policement to deter crimes, right? Between 10am till 1pm on Sunday 22/11/09, 3 patrol cars parked by the road between Kesas Highway and OUG. The men put cones to narrow passge to one lane- few of them checked on motocylists (mostly) and motorists, while one stood to direct traffic. Their action did not look an 'operation', more adhoc type. Even if they intend to deter crime, why 3 patrol cars parked at same spot, back-to-back at this spot? These men wasted expensive and useful assets to deter crime in OUG and surrounding areas!
