And I would agree that that would be a legitimate airport use, no question.

I'm still curious as to why I've never seen a homeless person or homeless people hanging out at airports, though? Personally I think they'd be a great public place to hang out at if I were homeless. How often can you hang out at a library?

You've obviously never been to ATL.

Because you have to walk probably 10 miles to the airport. And if you get thrown out you have to walk 10 miles back to the library. ;)

Actually there's probably some truth to that. We never had a "homeless problem"*, but we were a considerable distance (7-10 miles) from where a good chunk of the homeless population existed.

And then:
I'll yield to your superior knowledge of US law, but I stand by my calling you out on your message. Your reply post limited it to US citizens in the USA, which may be true (I don't know). Your original post was
which is demonstrably false (counterexamples including aliens in many US states, everyone in Germany).

America is not the world.

Germany still has not learned that "Where are your papers?" makes for bad PR?

This thread was relevant to American law, as was my reply, but yes, other countries are not bound by the US Supreme Court. :) That said, despite spending ~2 months per year abroad, the only time I've ever been asked for my ID by a government official in a foreign country, besides for transportation/immigrations/etc., was when a police officer told me I couldn't drink vodka on the streets of St. Petersburg (which was a surprise to me... I thought it would be viewed the same as a water bottle in Russia... who knew??). I do know that being "the wrong color" can increase your odds in many countries, though.

And a couple overseas. I've seen homeless at a couple of small (general aviation) airports.

Most US airports are not in the city nor do they have public transportation readily available. That makes it much, much harder to be attractive to the homeless.

Question About ID Number?
 

:) I ONLY carry ID when driving as I no longer fly inside the U.S.
I was wondering what happens if a LEO legitimately wants to see ID
(which I don't carry) BUT I tell them I can provide the DL# if you want to pull up the info and photo on the computer.
My logic says that should work but many have found that their rules depend on how they feel at any given moment.
Thoughts about this....anyone.:D

You'd be fine with that. Others will tell you that you don't have to provide an ID card nor are you required to carry one, and they're right. However, in the jurisdictions that have a requirement that you identify yourself to an officer, they will do exactly what you described. They'll either run you on the in car MDT or ask their dispatcher to do it for them.

Honestly, as a LEO, I am surprised when someone actually has their ID on them. Normally, I ask for ID, they say they don't have it, I ask for their name and DOB. One quick NCIC check later and they are either on their way or in handcuffs.
