In a truly exclusive expose, innocuous looking anti-smog guns presently are openly criss-crossing the VIP areas of Delhi in the garb of checking menacing pollution in the city but, reliably understandably, they are real guns fully capable of providing full protection to the VIPs concerned.
Though officially not yet clarified to avoid obvious (instant) panic among the citizens --- open gun-movements in Delhi-roads is a "never-sight" unlike in many European etc cities --- hence break down in law and order is best avoided in the garb of taking refuge in anti-pollution vehicles spraying smogs to depollute areas.
These otherwise menacing looking "anti-pollutant vehicles" undoubtedly look menacing in the city's VIP areas but they are a must necessity to avoid "enemies of all hues if infiltrating in the VIP areas to create havoc".
More details on this are not available for strict security reasons, it is reliably understood.
