Re: BB's death was not caused by bullets or bomb fragments
She has been attacked b4 just like that but she got lucky. Now, if I was her and have been attacked once like that then being smart I would try to avoid that for next time, even though she was coming right out giving her speech.
1 - possible that someone who was involved from inside persuade her to stand up n wave once more right the moment when target was ready.
2 - may be she was too excited and confident about her speech n stuff that she totally forgot about the danger that was lying ahead of her.
Allah knows better but people need to do investigation properly instead of comign up with different theories about her death.
That was not the first time she was standing out of sunroof, she did the same thing couple of times, In one video she was standing with Naheed khan so basically the bomber knew she would do something like tht again
