A story from a retired Chicago policeman:
A tractor trailer hauling hogs overturned in the s-curves near the loop. The hogs got out and were wandering the freeway. The cops at the scene were trying to figure out what to do. One cop decided the best option was to shoot them so he took aim and shot. The first shot just pissed off the pig and sent the others running. This led to all officers firing, expending over 100 rounds before all the pigs were killed.
Of course, now they had to try remove the dead pigs from the freeway, but it was night so they got a snow plow and plowed the pigs to the curb so they could clean up in the morning.
Turns out that word got out about the pig slaughter. By the time the cleanup crew arrived the next morning, all the pigs were gone. There happened to be many a pig roast on the southside, westside and northside over the next few days...
To hear the retired cop tell the story was priceless. The laughter brought tears to the eyes for all of us.
