I'm sure glad to see stories like this one where terrorists are caught BEFORE they carry out their terrorist activities. As 911 demonstrated if we wait until the crime is committed, dozens, hundreds and even thousands of lives are in jeopardy.
I fully support a government that aggressively hunts down terrorist plans and nips them in the bud before they are acted out. Problem is what can you do to those who are caught? If they acted out their plan of mass murder, it would be generous to give them a lethal injection. What can you do to prevent them from becoming a threat in the future?
