always reminds me, is the TSA's liquid carrying exemption for saline solution, or bottles that say saline solution?
>Later, Schneier would carry two bottles labeled saline solution—24 ounces in total—through security. An officer asked him why he needed two bottles. “Two eyes,” he said. He was allowed to keep the bottles.

On the other hand, I've accidentally left large bottles of contact solution in my bags more than once (when I expected to check a bag but ended up doing carryon, and forgot to repack the liquids), and never been stopped for it. 100% security theater
