There are valid reasons for PETN to be moving through that port, the punctures concern me. Makes me wonder if some amish were taking pot shots at them.

My understanding is that PETN is normally shipped ‘wet’. It is much more volatile when it dries out.

Maybe puncturing the containers would cause the PETN to dry out. If the puncture marks are small enough that they were only discovered by good luck then the terrorist goal was that they would explode automatically when they dry out enough, or possibly normal activites like moving the containers would cause them to explode.
