*The LA Times is reporting that a woman who pepper-sprayed other shoppers Thursday night at the Wal-Mart in the Porter Ranch area of Los Angeles armed herself with the caustic spray to gain an advantage in the fight for merchandise at the Black Friday sale, a fire captain said.

The woman, who is still being sought, used the spray in more than one area of the Wal-Mart “to gain preferred access to a variety of locations in the store,” said Los Angeles Fire Capt. James Carson.

20 customers, including children, were hurt in the 10:10 p.m. incident, officials said. Shoppers complained of minor skin and eye irritation and sore throats.

“This was customer-versus-customer ‘shopping rage,'” said Los Angeles Police Lt. Abel Parga

Meanwhile, in San Leandro (in Northern California), a Wal-Mart shopper walking to his car was shot and wounded in a suspected robbery early Friday.

Another shooting was reported at a parking lot next to a Wal-Mart in South Carolina, also a suspected robbery attempt.
