The document discusses the effectiveness of gun control laws in the United States. It notes that mass shootings have increased in the US compared to other nations that enacted stricter gun laws after similar tragedies. While opponents argue that people have a right to self-defense and that people not guns kill people, the document counters that guns make it much easier to kill others in mass shootings and criminals should not have easy access to deadly weapons. It also argues that investing in mental health programs could help address the root causes behind some mass shootings in the US by those suffering from mental illness and depression. Stricter background checks and limiting access to firearms is presented as an effective first step to curb gun violence.
