If someone chooses to endanger their neighbors by bringing dangerous, explosive materials into a densely populated living area that shows a very bad decision making process at minimum, and at worst malicious intent. That's something that others need to know about, in order to protect themselves and their families.

What you are calling "running their mouth" is the community protecting itself from someone who has already considerably disrespected the safety and lives of the community.
