"Republican presidential candidate Herman Cain said Saturday that part of his immigration policy would be to build an electrified fence on the country’s border with Mexico that could kill people trying to enter the country illegally.

The remarks...drew loud cheers from crowds of several hundred people at each rally...Mr. Cain added that he also would consider using military troops “with real guns and real bullets” on the border to stop illegal immigration.

The remarks were among the most pointed yet by Mr. Cain about illegal immigration...
It is not the first time that Mr. Cain has floated the idea of an electrified fence...
In his remarks on Saturday, Mr. Cain appeared to go a step further. ... Mr. Cain said that part of his plan would be to “secure the border for real” with a fence.

“It’s going to be 20 feet high. It’s going to have barbed wire on the top. It’s going to be electrified. And there’s going to be a sign on the other side saying, ‘It will kill you — Warning.’” At an earlier rally...he added that the sign would be written “in English and in Spanish.”

Cain Proposes Electrified Border Fence

The next day, however, Herman Cain said he'd only been joking:

"That's a joke,” Mr. Cain told the journalist David Gregory during an appearance on NBC’s “Meet the Press,” where he was asked about the electrified fence. “That’s not a serious plan. I’ve also said America needs to get a sense of humor.”
Cain Says His Deadly Fence Plan was 'a Joke'

So does that mean that Cain is against a fence, or for a fence but not an electrified fence?

Does Cain realize that he's running for president and everything he says can be analyzed, examined and used against him?

In the future, maybe Herman Cain could tell us when he's serious and when he's joking.
