TBH, our freedoms have been eroded for a long time.
There is now talk of 'assessor' being able to enter one's house without warrant for 'rating' purposes. I'm damned if I'm having that.
We get fucked in every hole taxation wise for ever more inept government.
It's not a Police State, since by and large, the Police don't want the extra work, preferring to do the job they signed up for, which is stop crime, not hoover up extra revenue for venal and grasping government. When the new intake are saying that the 'job is fucked' within weeks of basic training. IT was usually the 20 year men who said that.
So, it's not a Police state, just ever more opressive government. There would have to be a major sea change,and the institution of something like the wider Patriot Act stuff in the states to be enacted here... which there is in terms of
The Legislative and Regulatory Reform Bill which superficially looks different but means people can enact laws to do what the hell they like.
