The problem is not specifically criminals, but how people react to others under stress, and how they view guns in their lives. Do they turn to guns quickly, or do they find peaceful solutions? The posted signs are one way to judge, and I really do hope most people are peaceful, even though they portray violence. My family's safety could depend on their true nature.
An example of someone's recent true nature:
>> A Washington man was arrested after officials said he shot and killed a neighbor for revving his engine too loudly.
