A protest by university students closed the entrance of Mobile World Congress Wednesday and choked off physical traffic around the venue.
Here, armed policemen stand guard, preventing anyone--protesters or convention goers--to enter MWC, which is held at the Fira de Barcelona-Montjuic.
Two rows of heavily armed policemen prevent anyone from entering the Fira.
The police aren't messing around, and are fully prepared to meet the protesters.
The protesters happened to be near the neighboring hotel, which played host to Microsoft's Windows exhibit. Fortunately, Microsoft held its Windows 8 consumer preview event offsite.
The protesters weren't particularly aggressive, with many quietly standing or sitting around.
