NOGALES RAZOR WIRE: City of Nogales Deputy City Manager John Kissinger discusses the city's opposition to added concertina wiring, often described as razor wire, that extends to the ground of existing barriers at the border. COMMUNITY REACTIONS TO THE WIRE: Arizona 360 gets reaction from people in the community and travelers about stepped-up measures to secure the border. NOGALES BORDER PATROL CHIEF: Not all border communities have had concertina wiring added to existing barriers like the City of Nogales. The patrol agent in charge of the Border Patrol's Nogales Station discusses the decision to install the wiring in Nogales. PRIVATELY FUNDING THE WALL: The founder of a non-profit attempting to fundraise to build a stronger border wall on private lands spoke about his motivations with Lorraine Rivera shortly after a town hall the group held in Southern Arizona. ANGEL PARENTS: The parents of two men killed in separate instances by immigrants in the country illegally speak to Arizona 360 about the causes they've taken up since their sons' deaths. Lorraine Rivera spoke to Mary Ann Monedoza, whose son, Brandon Mendoza, was a Mesa police officer killed in 2014 by a wrong-way driver. The father of Grant Ronnebeck also speaks out about his son's death. Ronnebeck was shot and killed in 2015 by a disgruntled customer as he worked at a convenience store in Mesa. IMMIGRANT CRIME RATES: Proponents of increased border security often argue that immigrants who cross the border illegally go on to commit violent crimes in the United States. However, many reports show that proportionally immigrants in the country illegally are convicted of violent crime at lower rates than citizens. Arizona 360 hears from the author of one of these reports, Alex Nowrasteh of the Cato Institute.
