You are right, we are fast approaching a global police state. The 'people of tolerance' need to quit being so intolerant of others before they find themselves the target.
Uhg.
Cameras and noise monitors on street corners are not global anything. It's local control of locally owned property.
Can the shareholders of a company ask that cameras be put in the work place? Local governments are similar in that the residents are in effect shareholders of the areas held in common. Do they have a right to do what they want with their property?
