According to this report on the Egyptian newspaper/website Al-Youm 7, a man from Suez, entering the Square (which as I've noted before, is round) in recent days, was found by the "Popular Committee" controlling access to the Square to have a bottle of wine with him. He was seized and kicked out of the Square, and if this photo (with the paper's watermark intact) is correct it may have been poured out on his head.
Now who, precisely, controls the "Popular Committees" controlling access to Tahrir isn't clear, but the relatively brief account calls him ahad al-baltagiyya, "one of the thugs," though it also says he was a worker from Suez who came to Cairo looking for a job. How does an unemployed man from perhaps the angriest city in Egypt become a baltagi? Just because he was carrying a bottle of wine?
The picture here and others at the link don't look like his challengers were Brotherhood or other Salafis; no beards in evidence. I can think of other reasons for their anger, but none are supported by the limited information available:
- Were the protesters concerned that he would lead the authorities to claim there was a drunken orgy going on in Tahrir?
- Or were these Islamists without the trademark beards?
- Or is the issue that he was an outsider and falsely suspected of infiltration?
Of course, maybe he was a baltagi, but nothing in the story or pictures suggests so. He looks like a job-seeker caught sneaking wine through a checkpoint.
And given what I've seen of Youm 7, this could be tabloid sensationalism and nothing more. The information's awfully sparse.
