(CNN) -- One of the biggest holiday weeks is upon us. Thanksgiving is a favorite day for football fans, close-knit families, families who can't stand each other, and of course, amateur competitive eaters. But what's really interesting about Thanksgiving is the day after -- known as Black Friday. It may well be the most publicized -- and puzzling -- commercial day of the year. According to the National Retail Federation, last year's Black Friday attracted more than 90 million online and in-store shoppers. Online shoppers can buy things from the comfort and safety of their homes. But what about those who succumb to mass hysteria at local megastores? We have all seen the "shopacalypse" on the evening news, which appears constrained only by the flimsy protection of a few Tensabarriers and some security guys.

The bottom line is that stores will be liable if people are injured by known, unsafe and nonobvious conditions on their property on @placeholder, especially if stores take no special safety or security precautions, and treat the day like any other day.
