Mumbai Blasts

It happened yesterday around 7 pm within 10 minutes at 3 different places in Mumbai.
In my view, the blasts are the results of internal gang war between the two mumbai underworld gangs, for the control of the city. the govt keeps on changing but the criminal elements exist and have a strong group. the blasts were low intensity.. the terrorists will never do that (the places were crowded places. The blasts happened on a wednesday. If they wanted to kill ppl, they would have made bigger blasts. Clearly the intentions arent for terrorism. It could be a signal to the govt about their parallel power, it could be a black mail,  it could be some 'biz'men behind) . The immediate ppl who come to the mind are the underworld guys.. The no of deaths = 21... Not a number any terrorist org would aim for...

update (9.56am) : Is it the entire responsibility of the politicians? Putting my foot in their shoe,the first question that comes to my  mind is how do i identify the culprits? - They are the citizens of india too.. (coz these guys grew from mumbai slums )
