Nigerian Terrorists

We can detect explosives at airport security checkpoints, so the next step for the terrorists is to bring chemicals that can be mixed to produce explosives. On Friday a Nigerian terrorist tried to mix chemicals at his seat and just managed to burn himself. I'm not sure why he didn't do it in the lavatory. On Sunday another Nigerian on the same flight barricaded himself in the lavatory. Is it not obvious what is going on? They are experimenting. They want to know how long they have to work in the john. But all the news media are describing it as a false alarm.

I hope our homeland security people are smarter than our journalists.
