The wall was never a stand alone solution and every single hater here knows it & are just being disingenuous. There is no way to completely stop the crime wave of illegals and cartels from entering the US. The idea, from the get-go was always to build the wall as a deterrent, and if penetrated, Border Patrol would be alerted & they could respond to it. Trump's plan was the wall, bolstered by more lighting, electronic monitoring and more Border Patrol agents to respond if/when penetrated. This tweet is quite obviously not proof that the wall isn't working.
