KNOXVILLE – Mayor Haslam has approved the construction of a fence along parts of the Knoxville border aimed at preventing outsiders from benefiting from city services for free. Supporters said the fence would cut down on crime and drug smuggling. But Steve Hall, fence opponent and City Council Member, was quick to point out that “…the wily outsiders will simply tunnel under the fence; making it obsolete within a year. And we all know that the Knox County mole people already have a series of tunnels that can be tapped into.â€
