The retired general Ãngel Vivas thinks in black and white. He hates the Castro brothers on Cuba. He loves SimÃ³n BolÃvar. During the protests against president Nicolas Maduro, he explained in a tweet how to stretch up a steel rope over a street. Maduro demanded his arrest when a motor bike driver got killed by a rope. Vivas fought back. When security forces tried to arrest him in his house, he refused to hand himself in and appeared on the roof of his house with a M16 rifle. Since that day, he has not left his home for fear he could be detained. As he canÂ´t go out, I went in.
