Very unfortunate incidence.
Theft of aesthetic fittings of HS, Mahamana etc, and stone pelting on Tejs ans earlier of new imported NDLS-LKO Shatabdi rake presents a very sorry picture about our country and its citizens.
Reasons are many like:
(1) Destructive mentality of a section of people
(2)...
more... poor law & order (no fear of law of Land as well as God) among huge chunk of population
(3) Corruption in organisation- which readily "tolerates" incessant thefts of Rly properties and does not take adequate action to stop it.
