This is an accident and what's remaining is Search & Rescue.
The other is terrorism and is still on going. And it's not 3 people now. 5 people already (one is a suspect and another a policeman) The fugitive is armed and dangerous (including explosive devices) at large in residential area.
But we should not feel sorry for those who lost their lives in Texas?
Media giving lots of attention and love to the 3 that died in Boston, which I have no problem with by the way... the issue lies within the fact that there's no love and attention by the media for Texas casualties.
