I don't think it is possible to outlaw what is really nothing more than a sale.
People have been injured and even killed being trampled by bargain hunters.
We have to accept that people are really stupid selfish creatures. So long as there are people these things will happen.
In the case of the woman who pepper-sprayed the crowd; she should be made an example of. I would have no problem putting her in prison for 1 year / each person injured. She very easily could have gotten someone killed. Simply charging her with battery isn't nearly enough.
As for Black Friday BS in general and all of the hooting about how it is intruding into people's TG holiday? If you are so lame that you are going to some BF event you are to blame for anything that interrupts your TG.
I will be watching you on the news and laughing my self silly.
But I don't buy into the whole Xmas thing. My family doesn't do the whole commercial Xmas thing. I do any shopping I need to do, which for Xmas is 0, online. Everything comes to my door and I get better prices than any BF sale; or I don't buy it until I can.
Stores should be ready with decent crowd control. But if they aren't they can deal with the trashing of their stores and any law suits that come as a result of their stupidity.
