Every day terrorists develop new means to carry out their dastardly act to achieve maximum impact. Whether the strategy is new or old from ages past the most important thing is that it is wrong and its even more unsafe to have a social life for innocent citizens who wants to just live their lives in peace and the onus will be on government to really step up their game and protect us because for me now if I say I wont go to some specific places because of terrorism, will I also not want to spend time with family or I start running from trucks when I see one? Its a serious issue that should be looked into.
