Terrorist And Bomb Scares...

... are in the news today especially since those ever persistent authorities in New York City went on a few raids of some apartments in which the cops were looking for evidence of explosives used for homemade bombs. Of course, the cops found nothing of the sort but that hasn't stopped
Counterterrorism officials from issuing warnings to police departments all over America to be on the lookout for such items. Of course, those in New York were also looking for links to al-Qaida operatives. I take it that none of those were found either.

The joint FBI and Homeland Security intelligence warning, issued Monday, lists indicators that could tip off police to homemade hydrogen peroxide-based explosives, such as people with burn marks on their hands, face or arms; foul odors coming from a room or building; and large industrial fans or multiple window fans. The warning, obtained by The Associated Press, also said that these homemade explosive materials can be hidden in backpacks, suitcases or plastic containers.
