New submitter Calibax writes "30 years ago, Bob Wallace and his partner came up with a product to help hikers, flood victims and others purify water. Wallace, now 88 years old, packs his product by hand in his garage, stores it in his backyard shed and sells it for $6.50. Recently, the DEA has been hassling him because his product uses crystalline iodine. He has been refused a license to purchase the iodine because it can be used in the production of crystal meth, and as a result he is now out of business. A DEA spokesman describes this as 'collateral damage' not resulting from DEA regulations but from the selfish actions of criminals."
