I fear that within another 10 years it won't just be airports. I wouldn't be surprised to see this type of "security" at train/bus stations, stadiums, movie theaters, churches, etc.
So you mightn't even have to wait 10 years!

if somehow you run out of fear, just declare it a right that all are by being human entitled to and fall back, its for the children.
people are easy to exploit, that is why both corporations and politicians have marketing teams. they might call those teams by different names but the end result is the same, to get the public to go along with the desire of those who want money from, support of, or control over.
Aside from stadiums which are almost as ridiculous with their security protocols solely to get lower insurance bills (usually by contracting security staff on event day with the cheapest contractor at the time), security is shit enough at these places and there's zero money to do anything about it.
Many LA metro stations don't even have turn styles or staff beyond the guy sitting in the front of the train; people walk onto the train and sit down without paying. Bus stations are commonly just a tiny metal sign attached to something already upright. Churches can barely afford their buildings as they stand. Movie theaters, not much better situation there. These places can't even afford a mall cop.
A quote:
> If you fly within the United States or enter secure federal buildings and military bases, you will need a valid passport or other federally approved document, such as a REAL ID driver license or identification card, beginning October 1, 2020.
So, we need a passport to go between states, or a REAL ID...
