Comment Re:Embassi in Laos (Score 1) 509
I have no idea what the laws are in Laos, or how far past the foundation the US soil extends, but photography is a serious security threat in some circumstances. For example, one of Sean Smith's last messages to the outside world was "Assuming we don't die tonight. We saw one of our 'police' that guard the compound taking pictures."
The catch is that it isn't really stoppable, or even necessarily chargeable in most places. About the best they can do usually is to estimate the threat by ordering the photographer to stop and seeing how that conversation goes. You'll notice that in your encounter, the worst that happened to you is that you got annoyed.
(For the record, I'm 100% against laws that prohibit photography of any one or any thing, in the public, in the US.)
