I guess that must be sick in the "pyrotechnics are fun" way, not sick in the neighborhood cat lady prying into other's possessions and then running their mouth about it to the news, sort of way.
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.
