And, about the knives, I will probably be happy to carry one in a few years time. Atm, i'm a teenager with long hair and an affinity for fingerless gloves and that looks angry when walking through places with a high concentration of policemen (nothing against policemen, they just reside in areas where there are also high concentrations of thugs, pregnant teenagers, ram-it-in-your-face dogmatic Christian preachers and various other forms of shit). So i'm a prime target to be searched. And, i don't own a huge amount of knives so i wouldn't want them to be taken off me. Also, i'm absolutely tiny so if that's what policemen base their searchings on, i'm a prime suspect.
