Leaders of "free" Western countries are following the path of
tyrannical countries such as China and Russia when they demand
total
surveillance power.
No amount of "security measures" can perfectly prevent all terrorist
attacks, so there will always be more excuses for added "security
measures". And note how the number of victims needed to make an
excuse keeps going down. The French terrorists killed fewer than 20
people, which is surely fewer than are killed on French roads by car
accidents every day, and attacks on human rights are proposed on this
basis.
