Hurricane season is here. Why are we worried about the possibility someone "might" try to unlawful enter a mobile home in a park with a 500/10 chance the key might work?

The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it.
