Is humanity in the final steps of becoming into slavery?:
Thanks for bringing up this important issue.
Most of the things you mentioned have beneficial uses.  The danger if they are misused.  I think the Bush administration has demonstrated how our rights can be undermined.  They are talking of retaining the prisoners in Cuba for the rest of their lives, without charges or benefit of legal defense.
The only way to protect our rights is to participate in the process of government.  I hope anyone who reads this is ready to defend liberty with their vote on the 7th.
