Our US constitution permits the right for all citizens to bear arms, making the country wide banning of guns extraordinarily difficult to achieve and technically unconstitutional.
I dislike guns and am all for stricter gun laws to prevent further tragedies from occurring, but at the same time... banning everything would place an enormous amount of power into the hands of the sick individual who freely disobeys the law.
I don't know what the solution is.
Edit: To the people saying "the police wouldn't lose their guns if stricter laws were enforced!"... no duh. This is a joke, not a depiction of a realistic scenario or a blueprint for a flawed solution.
Outside that, I truly appreciate the number of thoughtful discussions that are going on as a result of this illustration! It's really awesome to see so many people being respectful to each other when discussing such complex issues. Thank you everyone for being so mature about this topic and I look forward to reading your discussions more in depth.
