Many people have been discussing the topic of weather or not schools
should start putting in metal detectors at all of the schools. While
half of the people are agreeing that metal detectors should be put into
the schools, the other half thinks that metal detectors create a false
sense of security for a high amount of money. Expert Dennis Kenny says
that "with all of those windows and doors that don't lock all the time,
there are multiple ways of bypassing a metal detector.
Metal detectors do create a false sense of security about keeping out
unwanted objects. While metal detectors might be able to keep out some
metal objects, they are unable to keep out the items that are not
metal but are illegal.
