Even the forensic laboratory will not be able to 
tell you how big the charge had been, what type of charge had been 
used.  They would only be able to tell you what kind of elements had 
been used in the manufacture of the explosives.  That would be all 
that they could tell you.  They wouldn't be able to tell you how big 
it had been, what kind it had been etc.  Only the type of explosive 
used.
