Man trampled at Wal-Mart

This is a very sad story. An employee at Wal-Mart was trampled over and killed during the black Friday shopping event; just as bad was that people continued to shop while the injured employee was receiving first aid from paramedics and were even pushing the paramedics around. Its amazing that this stuff still happens after so many black Friday experiences. I would think that retailers would have figured something out by now to keep everyone as safe as possible. I realize it must be hard and that people must also modify their behavior in order to prevent this kind of thing from happening, but I do think that retailers must do their part to ensure that people have a safe shopping experience. After all, they are inviting people to come in t0 their locations and shop, so they are charged with taking necessary precautions to ensure that everyone has a safe trip. I've seen some retailers set up lines outside of their locations with security guards and let a fixed number of people go in and shop at a time. Maybe that is just what needs to happen because I don't think that saving a couple hundred bucks is worth dying for. Obviously, whatever safety precautions are currently in place right now are not working.
