Al-Megrahi's conviction was largely based on the testimony of a shopkeeper who identified him as having bought a man's shirt in his store in Malta. Scraps of the garment were later found wrapped around a timing device discovered in the wreckage of the airliner. Critics of al-Megrahi's conviction question the reliability of the store owner's evidence.

Is this true? I hope there was more to the evidence than this.
