What significant act was signed by G.W. Bush on July 22, 2004?

The significant act signed by George W. Bush on July 22, 2004, is known as the Law Enforcement Officer Safety Act (LEOSA). This law enables qualified law enforcement officers and retired law enforcement officers to carry concealed firearms in most jurisdictions, thereby enhancing their ability to protect themselves and the community even after retirement.

The rationale behind this act was to ensure that those who have dedicated their careers to law enforcement are still afforded the means for self-defense and can respond to potential threats even after they have left active duty. It recognizes the importance of the experience and training that these individuals possess, contributing to public safety.

The other options relate to various aspects of gun laws and policies but do not align with the specific act that was enacted on the given date. Therefore, the Law Enforcement Officer Safety Act stands out as the correct answer.
