What is considered illegal use of a firearm under California law?

Using a firearm in a reckless or negligent manner is considered illegal under California law because it endangers the safety of individuals and the public. Recklessness or negligence implies a disregard for the safety of others and the consequences of one's actions. Specific behaviors that fall under this category could include firing a gun in a populated area or handling a firearm without proper precautions, which can lead to accidents or injuries. Laws in California are designed to maintain public safety, and actions that pose a significant risk to others are strictly prohibited.

Practicing in a confined space may raise safety concerns but is not inherently illegal unless specific ordinances are violated, such as concerning noise or property rights. Firing at a target greater than 500 yards is not illegal as long as it is done safely and in compliance with local laws. Lastly, transporting firearms without a permit is a serious issue, but it relates more to permit and registration requirements rather than the actual use of firearms in a way that poses direct harm to others.
