It's police bonus time around here, they pick out the good 'uns from the 'amnesty' and sell them on ebay....
it's not illegal to own most of them, so i'm not sure why anyone would turn them in in the first place, balisongs, push daggers, gravity knives, sword canes, switchblades and a couple more specific types are banned from sale, trade, loan, or carry, but can be kept around the house if owned from before the law took effect (1988) but you can carry a three inch max non-locking blade without worry, or a bigger locking/fixed one if you have a reasonable excuse (which you may need to argue in court from your holding cell if the police are being unfreindly)
there've been about 15,000 turned in so far & the police are overjoyed at their huge success in getting the evil weapons out of circulation (see para. 1) and showing the huge fantasy hibben-style pseudo-weapons on the TV news to let us know what evil items are being turned in. of course most of the 15,000 are steak knives, stanley knives, and linoleum cutters.
people who want to collect knives, or engage in hunting, fishing, or target shooting are to be considered abnormal, best educate that out of society.
we are being edjumacated into believing that all items are considered 'offensive' weapons and that there is no legitimate need for anyone to defend themselves. after all , that's what the police are for , isn't it.
of course the police don't think they are there to defend anyone, they are there to record statistics, fill out forms, as long after the fact as possible. after all , they might get hurt, they're unarmed you see. there is no statutory requirement for police to actually intercede to stop a crime, or even to attend afterwards! after all, on the occasions they do, they get roasted by the press for excess violence, and get sued, or fired by politicians, and all kinds of similar dis-incentives. better to be safe, and only raid law-abiding people's homes, it's safer, after all they've turned in all their guns and knives. raiding criminals homes is dangerous as they can defend themselves - best send in 250 armed swat team members with itchy trigger fingers to arrest suspects.
our courts of course, protect us from the criminals that manage to get caught (of course YOU may be a criminal for carrying an 'offensive' weapon, like a cane in a threatening manner). they are punished to the full extent of the law, like the farm owner who was jailed for three years for shooting a poor almost defenseless burglar (he only had a baseball bat), or the guy who was just sentanced to life for kidnapping and rapeing a three year old girl, who is eligable for parole in four years.
