Gareth's in Exeter, heading out to investigate reports of a group of youths in a lane behind a pub who've had a lot of alcohol, and a bit of a barney. One of them, it seems, has picked up a metal bar, so Finn has to stay put. He encounters a local officer who's stopped a cyclist, who isn't carrying a metal bar, but he is carrying a knife. He admits to this without hesitation, apparently under the impression that there's nothing wrong with going about in public armed with a six inch steak knife. Upon being informed otherwise, he decides to threaten to start spitting, and is immediately plonked on the ground. He then makes things a little worse by claiming to be HIV positive, which would make his saliva slightly more than just unpleasantly messy.
