Why we need a border fence

Here's a news story that tells that same sad old story: A U.S. Border Patrol agent is on routine patrol in the wee hours of the morning. He approaches three suspects near the international border. The suspects attack the agent and injure him before he manages to pull his gun and get off a couple of shots. Two of the suspects are arrested and one flees across the border. How many times have we heard -- Wait a minute. The Canadian border?

Extra points: Last October, 40 people were caught trying to illegally cross the border at the same Vermont town.

Double extra points: They were trying to sneak into Canada.
