The fight against terror is a hard situation where the victims are bound by the rules of civilization, while the attackers are barbarians fighting in gutters.
The earth, since it started forming 5 billion years back, has gone through natural processes of heating and cooling. Human contribution to global warming is negligible.
It is not justified that guards (or the system rather) let terror attacks continue on the one hand mistakenly and shoot innocent people like this Bangalore boy.
