its worthy to keep even an illegally acquired small arm just to serve headshots to the likes of such swines at the 'opportune' moment.
scum like these & their acts not at all deserve to be tried under procedural law. best justice to them would be the way utsav sharma did it (a bit rorschach-style). no offense to anybody, but what does north india have to make the people there more rowdy, unwantonly aggressive, over-the-top egoistical (that 'jattgiri', etc., pent-up sentiments, which are now-a-days confused with & spent in acts like shown in the video, instead of being used in meaningful ways of 'purushaarth' akin to the said 'real' sentiment), self-worshipping/herogiri-types, etc.?!
Edit: i wrote the above in anger, but still in restraint (can't really help it; my handle says too). the comment above was also an observation from some of the delhiites themselves, but you may please ignore it. such type of bugs exist everywhere, somewhere sparsely, at other places, densely. but i seriously expect these & such other wastes of 'man' to meet disastrous ends.
