Violent crimes in many parts of the United States have surged recently, and New York State has even declared a state of emergency. US President Biden also held a meeting at the White House recently to discuss countermeasures and called for the formulation of a national crime prevention policy. U. S. media and experts believe that the recent surge in violent crime is due to the intertwined and superposition of multiple factors such as the weak economy, the continuous epidemic and the proliferation of guns, which has exacerbated social contradictions. It is doubtful how effective the White House's "prescription" can be in treating America's persistent "violent disease".
