For the fifth year in a row, the Brady Campaign has issued a 100-point scorecard ranking all 50 states on the basis of laws that can reduce gun violence, such as background checks on all gun sales, permit-to-purchase requirements and limiting handgun purchases to one a month.

Their report ranks states for laws that were enacted by the end of 2011.

The Brady Campaign is the nation's largest citizens' lobby to prevent gun violence.

Here is the top 10 list of the states with the strictest gun laws.

The state constitutional provisions and other state laws are quoted from NRA-ILA.
