The police and military need guns that 'jam easily'

According to PA Governor Ed Rendell, anyway. About 37 seconds into the following video (not counting the annoying, ten second advertising segment first):

"It’s nuts for ordinary citizens to go out and buy assault weapons," Gov. Ed Rendell, D-Pa., told CNBC. "Assault weapons are difficult to operate, they jam easily. If you want a gun to protect your home it’s the last thing you should have.

"Assault weapons only have one purpose, Becky, and we should be clear about that. They fire at short range; they put out a ton of fire at one time; and they are very powerful.

Short range? How does the good Guv reconcile that with what he says a few seconds later?

The three Pittsburgh officers who were killed--one was killed by an AK-47. The AK-47 was so powerful that from a house a long distance away, it blew through a, uh, a police car--it just absolutely blew through the police car.

So which is it--"short range," or "from a house a long distance away"?

Now, to the money quote:

"These weapons have one purpose," added Rendell. " . . . They’re to kill and to maim, and they shouldn’t be in the hands of anyone else but the police and the military."

Because, apparently, the mission of the police is to kill and maim (and to do so with weapons that jam easily).

About 3:19 into it, he gets back to arguing that these firearms (the use of which by the police and military he endorses) jam, are "not very effective," and have no purpose but to kill or maim.

They use it ["it," in this case, being any firearm] to protect their house. If you have an assault weapon to protect your house, you're crazy. They jam, and they're not very effective. You should have a revolver, or something like that. There's no purpose for these guns but to kill or maim.

Says the firearms expert, Ed Rendell.
