Last year, when pepper spray was all the rage, a suburban Los Angeles woman allegedly sprayed other shoppers down at a local Walmart to give herself some space while trying to get access discounted Xbox 360s. The woman managed to flee the madness, but 20 people were injured, all thanks to her. Eventually, her conscience caught up with her and she turned herself in.

In a twist, 32-year-old Elizabeth Macias threatened to sue Walmart for failing to provide sufficient security during its Black Friday sale. Macias says that she deployed the pepper spray because her children were attacked while trying to get to the consoles. 

Whatever the reasons, it's all shameful.
