As the old proverb goes, if all you have is a hammer, everything looks like a nail. In other words, we tend to view solutions to problems from the perspective of the tools we have. This can be a problem when the tool is a deadly weapon. This is where pepper spray for concealed carriers comes in.
The situations that allow for use of deadly force are very few and far between; use of deadly force can only be in response to a threat of death or great bodily harm. Deadly force cannot be used to protect property or pets or in situations where the attacker does not have the ability to inflict death or great bodily harm.
