Editing Gun control (section)

====Studies of individual laws====
Other studies have examined trends in firearm-related deaths before and after gun control laws are either enacted or repealed. A 2004 study in the ''[[Journal of the American Medical Association]]'' found evidence that [[child access prevention law]]s were "associated with a modest reduction in suicide rates among youth aged 14 to 17 years".{{sfn|Webster et al.|2004}} 

Two 2015 studies found that the permit-to-purchase law passed in [[Connecticut]] in 1995 was associated with a reduction in firearm suicides and homicides.{{sfn|Crifasi et al.|2015}}{{sfn|Rudolph et al.|2015}} One of these studies also found that the repeal of Missouri's permit-to-purchase law was associated with "a 16.1% increase in firearm suicide rates",{{sfn|Crifasi et al.|2015}} and a 2014 study by the same research team found that the repeal of this law was associated with a 16% increase in homicide rates.{{sfn|Webster|Crifasi|Vernick|2014}} 

A 2000 study designed to assess the effectiveness of the [[Brady Handgun Violence Prevention Act]] found that the law was not associated with reductions in overall homicide or suicide rates, but that it was associated with a reduction in the firearm suicide rate among individuals aged 55 or older.{{sfn|Ludwig|Cook|2000}} 

A 1991 study looked at [[Washington, D.C.]]'s [[Firearms Control Regulations Act of 1975]], which banned its residents from owning all guns except certain [[shotgun]]s and sporting [[rifle]]s, which were also required to be stored unloaded, disassembled, or with a [[trigger lock]] in their owners' homes.<ref>{{cite web | url=https://www.nytimes.com/2010/01/11/sports/basketball/11arenas.html | title=Washington's Gun Past Affects Arenas's Future | website=New York Times | date=10 January 2010 | access-date=6 December 2015 | author=Abrams, Jonathan | archive-date=2017-06-30  | archive-url=https://web.archive.org/web/20170630060952/http://www.nytimes.com/2010/01/11/sports/basketball/11arenas.html | url-status=live }}</ref> The study found that the law's enactment was associated with "a prompt decline in homicides and suicides by firearms in the District of Columbia".{{sfn|Loftin et al.|1991}} A 1996 study reanalyzed this data and reached a significantly different conclusion as to the effectiveness of this law.{{sfn|Britt|Kleck|Bordua|1996}}
