Chacheing is one of those ideas created by somebody with his Rambo headband tied to tight. I am amazed at firearm and knife forums where legal restrictions are agonized over in between 30 minute downloads of personal collections shown off like some bowling trophy. If you have the prescience to stockpile have the equal prescience to follow survival guru Elmer Fudd's sage advise- " Be wery wery quiet." You could also use ' the lizard's gambit ' in surrendering a few bottles of tap filled water juggs and a can of SPAMM if people suspect you have anything. Look bereft while they take it.
