This Ain't Hell has picked up this juicy tidbit:
"Vietnam-era helicopter pilot was arrested in Dearborn, MI yesterday for plotting to illuminating the night sky over a mosque there. It’s funny how the media describes the plot in their headlines. The Chicago Tribune says 63-year-old Roger Stockham was arrested with explosives..."
Yeah, it's true that fireworks contain small amounts of "explosive material," packaged so that users have a difficult (but possible) chance of hurting even themselves if they misuse the fireworks in a grossly negligent manner. Fireworks are not an efficient means of attaining explosive material. They have a very small amount of black powder wrapped tightly in paper to cause more bang than damage.
Additionally, it appears Stockholm may even be a Muslim convert. Dearborn, MI has the largest concentration of Arabs outside of the Middle East.
