Terrorist plot?

I was reading about the terrorist plot in NYC. I do a lot of consulting (as an adviser or expert witness) with lawyers representing Arab or Middle East defendants in cases around the US and Canada. In my experience, many of the horrific schemes and terrorist plots originate with government informers trying to entrap fanatical fools or crooks in some cases. So I wait before I believe what I read. I once read about a group of dangerous terrorists only to be hired by lawyers representing them. It turned out that they were crooks and thugs but not terrorists.
