Terrorists have been entering the US across our southern border for years and the government well knows it. Illegal arms have also entered through those so called drug tunnels. It would be ice if we finally decided to plug up the holes but we also need to clean out the vermin already here.

Opinions are like assholes, everyone has one, some peoples stink more than others too. Remember, I can make your opinion disappear, you keep the stink.
