The general procedure is that a blast happens ,immediately the concerned Ploitician visits the Place provided he has time,or he will pass his condolences through media "Am feeling distressed .bla ... blaaaaa..."and then order an enquiry and then blame the Opposition.This is the general mandate of Indian Politics.....or Secular Congress Politics ...... Never take action against any one.....Gandhigiri slapped once show the other cheek...same way one blast show condolences dont take any action and cooly pave the way for othersss......
