Lol. What world does this author live in? I expect to be frisked every time I go to an airport or football game. I expect to have to turn my pockets out every time I cross the US-canada boarder. I'm not a minority, but I assume some who are will want to add to this train of thought re being frisked by cops.
And a warrant to search my home? Warrants are pieces of paper. Cops drive tanks and carry machine guns. Whether they bothered to phone a magistrate for permission before hand is the least of my concerns as they break down my door. Warrants only matter if they are going to charge me with something and want evidence admitted in court. Even then, there are so many exceptions. The evidence gets in. My concern isn't about paperwork, it's that I'll be swatted one night and they will shoot my dog.
Also, the "warrant requirement" is an American construct. It isn't a thing in places like Canada, which most would consider a very liberal democracy. Canadian cops can use evidence even if seized illegally. Nor do they have to stop questioning you if you demand a lawyer. Nor do you get a jury trial. Don't assume that all western democracies use the American legal system.
