@raphjd Justin Trudeau tried such measures in Canada. It failed miserably as many police forces refused to enforce the powers that he gave them on the grounds of them being unconstitutional... For example, Justin Trudeau gave police forces the power to stop people (like drivers) for no reason other than to question them about where they are going and why they are not at home like they're supposed to be. On the most part, most police forces refused to exercise this power. The closest that many of them came was setting up speed traps and pulling people over that they caught for speeding (a valid reason to otherwise pull them over even without the restrictions) and asked them the questions.
What's worse is that if you had to travel to and from work for some reason, you had to have papers from your employer with their contact information to vouch for your need to be out and about to travel to and from work. Also, you were only allowed to travel to and from work if the job that you do was considered "essential". If your job was not considered "essential" by the government's standards, you were SOL.
The other thing we saw was a restriction on what products you can buy. If the product was considered "essential" such as groceries, it was fair game, but things like clothing (including bras and underwear), and many other things you could reasonably argue are essential for some people were not allowed to be sold. It was insane... Going into Walmart and not being able to buy about 90% of the stuff on the shelves. It was insane. On that note, we even had a very interesting case that we came across where a man went to do his grocery shopping wearing nothing but a pair of tighty-whities. The media covered it extensively as it was considered so "groundbreaking in uncertain times". His claim (which I kind of agreed with) was that if clothing was not an "essential" item, then why is it required to do our shopping?
Getting stopped by the police, questioned, and needing papers in order to travel freely between places without police interference is awfully reminiscent of things we learned in history class, isn't it? Those times were very 1930's Germany, don't ya think?
