A sliding door had a regular doorknob ? <| sep |> Yeah . Easy money . <| sep |> Criminals don ' t obey laws , that sign only disarms those that do obey the lawIn regards to your edit , this is another fallacious line of reasoning . Many laws make things that are not by themselves dangerous but can help facilitate dangerous acts illegal . Having a gun certainly hurts nobody unless you start shooting people . Registering to vote many times hurts nobody unless you actually vote many times . Selling smallpox stock hurts nobody unless the person who bought it releases it into the public . Standing on a ranchers land i . e . trespassing hurts nobody . etc etc etcThe line of reasoning also assumes only bad people commit crimes . For example , a perfectly law abiding citizen might start shooting people if he had PTSD and had a gun with him . Whether to ban guns or not is a value judgment should people have to pay the cost of losing an ability in return for the benefit of preventing an X amount of harm . If you support gun control , then you think the deal is worth it , and if you don ' t then you think the deal isn ' t worth it . Nobody is wrong , they just have different values .
