If you rely upon news articles from the 12th of July, sure.
But since the 12th of July, the bomb factory was discovered, and a second bombing attempt failed because the explosives had degraded past the point of effectiveness, so investigators had pretty much all the information they needed to piece the case together.
The only thing you've got going for you is ignorance and the hope that everybody else is in the same state.
If any single peace of evidence would even in the slightest was involve Serbs in this matter, Serbs would be napalmed and nuked 10 times over.
I remember antiserbic hysteria when Oklahoma bombing happened, on on US TV (can`t remember which) jurnalist asked if there is Serb implicantion in that.
Can you remember when London explosions blasted off, articles were "Explosives tracking to Yugoslavia" and many articles were ready-to-accuse-and-convict Serbs, and just days later they corrected it into "racked to FORMER Yugoslavia" and than "Tracke to Bosnia" and now thay don`t have balls to say that mentioned cities and places including Vitez factory are in Muslim-Croate federation?
Is there gonna be "Explosives tracked to Muslims in bosnia" article?
No, I doubt.
