Starbucks @ Camp Delta
The action of some protestors in Brighton is documented in an Indymedia UK article, together with some photos.
They are protesting about the Starbucks outlet in the Guantanamo Bay military base. By being (willingly) present there they are showing compliance with the illegal detention without trial of the prisoners there, and upon knowing this, buying coffee at a Starbucks outlet can only be validating the crimes against humanity on the base.
Simple message: if you agree with me and think what's going on at Camp Delta is wrong (both legally and morally), don't buy Starbucks coffee.
As the above article says, "Please consider whether you want to support these crimes against humanity when you drink your coffee".
The same applies to McDonalds (naturally), Subway, Pizza Hut and KFC, all which, after a breif trawl on the internet, have outlets in GTMO.
