terrorist wannabees

Now that there have been arrests of what appear, from news reports, to be serious terrorist wannabees, there don't seem to be any more mentions of the young men who were arrested in Miami for talking about being terrorists. It sounded like the Miami group were like a lot of young people, talking about things they would probably never do, blowing off steam and trying to imress each other. Even the government said they didn't present a credible threat. So why were they arrested at this time? It is likely that after being arrested and imprisoned for such flimsy reasons, some of them will be even more angry and dangerous. I'm sure many people have joined me in wondering if the fact that this is an election year triggered the highly publicized arrest of the Miami group.
