The death penalty is most effective when it is carried out while the crime is still fresh in peoples minds.
The death penalty is never a deterrent for these people.
The State and the media are always trying to draw attention to the issue so they can divide the public, create controversy over civilian gun ownership and eventually confiscate guns.
If we need to underscore anything it’s exposing the media and the State’s desire for gun control. Keep things in perspective, mass shootings are a very rare cause of mortality. Democide, or death by government killed 250 million in the 20th century. People need to take responsibility for self defense and be aware of their surroundings.
