text: Has of recently we have had a various amount of school shootings in the united states and we have done absolutely nothing to stop it from happening. i belive our leaders have two options to stop this madness and it is either they make guns illigal and contrabands or they domesticalise this software devises to every school, so we may know the intentions of fellow student who come to schools to shoot it up. "Of course,most of us would have trouble actually describing each facial traits that convey happy, worried, etc" nick (5).this quote proves that we can not really tell what people intentions are by just looking at them, thats why we need this device in every school, airport, churche, court, and even home.
