Prompted by a recent topic about a certain notorious gun shop's questionable practices, I kind of wonder how people hear react if they're at something like a gun store, and they hear someone like the gun shop employee give blatantly erroneous information, whether it's just false, or even advice that if followed, could be potentially dangerous or illegal. For example, I was a gun shop in which a woman was shopping for a handgun, and said Glocks were recommended to her, and that she wanted compactness coupled with manageable recoil. The guy told her that G19 was the smallest-framed pistol that Glock offered (my guess is, the G19 is smallest Glock the shop happened to have in stock that day). Now, that's just bad/false information, but I've also heard gun shop employees giving potentially dangerous information, for example, that PSL rifles work best with heavy ball ammunition, when in fact a steady diet of anything other than light ball can damage, if not destroy the PSL. In any case, when this happens... what do you do you? Do you feel obligated in the interest of truth and propagating accurate information, and out of concern for the safety and well being of others, to chime in? Or do you feel as though anyone not prudent enough to do their own research is largely responsible if the ignorant and/or unscrupulous give them bad info?
