I boarded the bus.
I walked in the market with a big backpack.
Again nobody bothered.
What if I was one of them?
They can strike anywhere. Its just too easy.
How can we watch out everywhere?
They have such an easy task :P. The authorities have a very difficult task. Think about it.
Now you know Hindi picture mein Police end mein hi kyon aati hai.
How could they have known in advance?
