There's a couple of things that should be clarified in this response, I think:

5- Search United States Government sites. Many items are public domain and free to use
Two things,
1st - Just because an image is on a gov't site does not mean it is free to use. The gov't buys many images from commercial sites and the copyright still remains with the shooter unless noted otherwise in the image or exif file.
Absolutely true, and please be careful when looking to use images from Gov't sites (again, assuming U.S.).

2nd - Many gov't images are not at all free to use, Coast Guard, USPO, Blue Angels, Thunderbirds etc insignia are examples although you get a lot of leeway for editorial use if you take the picture. Otherwise the shooter is the owner unless released to Creative Commons etc.
If you can identify the owner, just ask for permission, you'll usually get it unless you're using it for commercial purposes.
All images produced by US government employees (federal) in the conduct of their duties to the government are free to use without restriction (
https://www.usa.gov/government-works). This includes the Coast Guard and Blue Angels (the USPS is a semi-public company with different restrictions), but remember that copyright is different than trademarks.
Also the copyright
always belongs to the creator otherwise, regardless of what type of licensing they place on their work (licensing creative commons does not relieve me of my copyright on an image - and in many places you
cannot divest yourself of your copyright to works (though you can license very liberally)).
Not trying to be pedantic, just wanted to make sure that this (
confusing) topic is not further muddied with misunderstandings.
