SNIPPET: "Prosecutors allege that Mehanna, 27, and a second man, Ahmad Abousamra, 28, formerly of Mansfield, tried to join a terrorist training camp overseas, but were rejected, then plotted to shoot shoppers at a suburban mall, but scrapped the plan because they could not get automatic weapons. They are also accused of plotting to kill two unidentified government officials. Mehanna also allegedly incited violence by translating pro-jihad materials from Arabic to English and posting them on the Web."
