To those who say they fit that .005% and therefore it's not fair to discriminate, ask yourself, if you saw a guy who reeked of booze, had a large combat knife in his hand, is twitching wildly, and is walking towards your kid, would you grab the kid and run? Would it be wrong to say you're discriminating because I was once holding a combat knife, twitching, and just had someone spill booze on me and I'm actually a real nice guy?
I say make up a story about your brother having a bike just like that and wanting to buy it to surprise him for his birthday. Hell, even offer the guy $100 plus a shiny new *FULL SUSPENSION* pacific mountain bike.
