A Tennessee jury found a prominent prison reform advocate guilty of vandalism Thursday after he disguised himself as a construction worker to hide guns, handcuff keys and hacksaw blades inside the walls of a Nashville jail under construction. Alex Friedmann was found guilty of vandalism over $250,000 in a case that a prosecutor likened to something out of a Hollywood movie. Much of it was caught on surveillance video and went undisputed. The prosecutor also said the case ends on a cliffhanger, leaving it anyone’s guess as to what Friedmann planned to do. He did not testify at trial.
