Final answer:
The predominant reason for the higher instances of gun violence in America compared to other advanced countries is multifaceted, including the easy accessibility of firearms, public misperception of crime rates, varying stances on the Second Amendment, misinformation from media, and a higher rate of very violent crimes facilitated by firearm access.
Step-by-step explanation:
The main cause behind the high number of gun violence cases in America is a complex issue, often attributed to multiple factors. Historically, the easy accessibility of firearms has been a critical point of contention. The tragic events, such as those at Columbine in 1999 and Sandy Hook in 2012, highlight this issue.
Statistically, despite a general decline in gun crime since the early 1990s, public perception still leans towards the belief that gun crime rates are rising or remaining high. Furthermore, the conflicting views on the Second Amendment and state cultures contribute to the varied stances on gun regulation across the nation, with some advocating for stricter gun control and others emphasizing gun rights. Also, the misinformation spread through various media outlets has skewed public understanding of the issue, leading to confusion and a cycle of violence. Lastly, America's high rates of very violent crimes, as compared to Europe, are also exacerbated by the ease of access to firearms, resulting in more opportunities to commit gun-related crimes and consequently longer sentences for American criminals.
