haha u still cant do that. different compounds appear as different colours in the scanner. so they could see weird colours of ur strong organic RDX compound! hmm but if u noticed the scanner didnt seem to be able to "see tru" the camera body itself.. seems like its too thick.. so well if u have a 1d series u know how big that battery is... LOL! u could shaft a whole strip of ur C4 in the battery compartment!
