"captured" vs. "arrested"

this stuff drives me crazy. there's a major double standard for the way the press describes the actions of a lot of different countries, but iran seems to get it worse than most. not that the iranian regime doesn't actually do all kinds of horrible stuff. but when they do ordinary things--stuff that wouldn't be considered wrong if any other country did it--like arresting people who illegally cross their border, their actions are inevitably described in the american press in language suggesting their actions are criminal.
