These kids have seen the non tolerance of elders and have in turn become non tolerant. Just imagine how a 14 years old kid not only got a gun but also got the guts to use it for a destructive purpose. Now a days it is very difficult to give examples of good, gentle and Exemplary behaviour. Elders instead of practicing and preaching good virtues now a days not only follow the wrong path but have also started justifying the wrong path.
