Heard about this on NRA News Cam & Company...on the Sportmans Channel.
The confusion and contradictions lead law-abiding gun owners to inadvertently butt heads with the law when they exercise their right to self-protection while traveling among states or temporarily living away from home.
An example is the Philadelphia, PA lady in August 2014 who obtained the necessary cc permit to carry her handgun in Pennsylvania, but was arrested in New Jersey for unlawful possession of a weapon. She was facing three years in prison for innocently disclosing that she had a firearm in her purse and a PA carry license for it to the New Jersey police officer who arrested her after a routine traffic stop. New Jersey has some of the strictest gun laws in the country and does NOT recognize carry permits from any other state.
She finally did get released on all the charges...
