From the big Dick:
It is good solid sound policy. It is, I'm convinced, one of the reasons we have not been attacked for the last four years. It's absolutely the right thing to do.I'd like to point out that my camel-repellent, which I have used faithfully for the past, like, decade, has kept my home and yard completely camel-free! If that's not proof of its efficacy, I don't know what is.
