Hey guess what . I did . And apparently have better comprehension . Here ' s what the article says The local sheriff ' s department told the Los Angeles Times that the explosion that injured Wilansky was not caused by police explosives , and alleged that protesters had been making their own explosives out of propane bottles , one of which may have blown up and hurt Wilansky . Protesters fiercely denied the charge , and Wilansky ' s father said that doctors had found evidence of a concussion grenade inside her body . A surgeon said he pulled shrapnel out of her arm , he said . It ' s pretty clear it ' s a grenade that caused this . So you ' re saying her father is a forensic expert who has analyzed the shrapnel and determined it ' s the right composition to be part of a concussion grenade ? Or no , the article doesn ' t say that , and you don ' t know whether the shrapnel is from a concussion grenade or an IED of some sort . So sure , I could read the article , but it won ' t answer my question in any way shape or form . So , for those who understand that there has been no proof presented so far , have you heard if they ' re going to test the shrapnel ?
