With just days to go before the Olympics start in Rio de Janeiro, Brazilian security forces have shifted their gaze to an even more amorphous crime: terrorism.They have increased checks at this border post - where tens of thousands of people cross back and forth every day - and have set up a control room with access to dozens of cameras watching different points of the frontier.Intelligence officials have long pointed to this border region, home to a sizable Muslim community, as a weak point in Brazilian security.With an estimated 500,000 foreigners descending on Rio for the Olympics and recent attacks on European cities raising security concerns, the daunting task of monitoring and controlling the border area between Brazil, Paraguay and Argentina has come back into focus.
It is often the most crowded crowd wherever Olympic is taking place. The riot control fence, as the name suggests, it is designed to control riot and crowd( that is why it is also called access control barricade, anti-riot barrier). But this is definitely not the only role, it is also commonly used at many public evens, such as sporting events parades, political rallies, demonstrations and outdoor festivals. It act as a physical and psychological barrier, used to demarcate ”no access” zones, which aimed at protecting performer from harm by crazy fans or malicious attacker.
