The right to bear arms in the U.S. for its citizens should not be allowed for all citizens, especially in regards to psychological issues. The news as of recently is showing that some citizens with gun rights may be psychologically unfit to have gun rights. Innocent humans are being shot at and killed by those that own guns. The animal world is being threatened by those that live to kill. If a human can kill an animal and not feel sad or upset that is a sign that they do suffer from psychological issues.
Currently in order to obtain a gun license or permit a fee must be paid, admitting any felonies, arrests, and any other criminal activity, and possibly going for a firearms course.
The requirements needed to obtain a gun license or permit are not enough and should be increased.
