宽松的隐蔽携带枪支法律是否增加了袭击事件?

近年来,枪支管制法律变化迅速;它们如何影响犯罪率是激烈争论的话题

7月20日在科罗拉多州奥罗拉市一家电影院发生的悲剧性枪击事件重新引发了关于枪支管制和允许公民携带隐蔽武器的法律的长期争论。一些人认为,电影院里武装的平民本可以减轻周五的屠杀,而另一些人则认为,更多的枪支可能会导致更大的混乱和更多的人员伤亡。

事实上,今天公民手中的枪支比以往任何时候都多。尽管美国成年人口中拥有枪支的比例较低,但那些拥有枪支的人拥有多支;每位拥有者的平均枪支数量从1994年的每人4.1支增加到2004年的6.9支。

随着枪支拥有量的增长,允许人们携带隐蔽武器的宽松法规也在增加。这些法律的增长非常明显。隐蔽携带法律可以是“必须颁发”或“可以颁发”的类型;在“必须颁发”的州,如果满足某些标准,执法部门必须颁发许可证,而在“可以颁发”的州,执法部门有酌处权。科罗拉多州是一个“必须颁发”的州,尽管一些企业,例如发生枪击事件的电影院,禁止在其场所携带枪支。

尽管最近发生了悲剧,但更多的州也在考虑允许在酒吧、教堂和大学校园携带隐蔽武器的立法。这两种趋势都令人担忧,因为它们在更多公共场所放置了更多隐藏的枪支。宽松的枪支管制法律是否会导致枪支暴力增加是一个激烈争论的问题,但有必要研究以确定这种关联的根源,以便立法者能够保护公民的生命和权利。
