Libertarians favor LEGAL immigration. We do not favor borders that look like swiss cheese, which is pretty much what we have along Mexico. If people from other countries want to emigrate to this country- no problemo! Follow the rules and come on over. If you sneak in, or are smuggled in, you are a criminal and you should be sent back.
Some people are beginning to see the presense of the Minutemen as a problem. From an AP story:
"We do not have the time nor the patience for anyone attempting to turn this situation into a three ring circus," Cochise County Sheriff Larry Dever said in a statement.
The Minutemen wouldn't even be there if the border was effectively being patrolled. Problem managed, no circus. Comprende?
