From what I can find, an average sweater uses between 3-6000 feet of yarn [1]. Apparently an 'ideal' altitude for for skydiving is 14000 feet [2]. That puts you around the same altitude as high altitude aerostat radar systems[3]. It would have to be a fairly voluminous sweater, but it's probably just about within the realms of possibility. It's chilly at that altitude, so maybe it was made with several layers for extra warmth?
I'm no wool-ologist, and even less of a jumper out of planes, but these were the sources I used to get my figures:

That's would appear to be the plan, yes. Push people to riot, declare marshal law, turn it into a full blown civil war and rely on the assumption that right wingnuts are more likely to be armed than those who oppose fascism. I fervently hope it does not come to that, and some way is found to stop it in time, but the future currently looks rather bleak in that respect.
