You’d expect campers, long lines and shopping mayhem on Black Friday, but injuries and violence? Here’s a look at some of the casualties of Black Friday mania.

‘Why did you throw him down so hard? All he did was shoplifting and you threw him down like that?’

This man, Jerald Allen Newman, age 54, reportedly hid a video game in his pants during the shopping chaos. A Wal-Mart employee pointed him out to police. Newman bolted for the door before police appear to have thrown him face first to the ground.

The most serious attack took place in a Wal-Mart parking lot in San Leandro, California around 1:45 a.m. after a shopper was shot for refusing to give up their purchases. KTVU reports:

“It appears the victims were walking to their car when multiple suspects confronted them, police said. After suspects asked the victims for their items and were refused, a fight ensued. One suspect pulled a gun and shot one of the victims... Family members wrestled down one of the suspects as another fled.”

Black Friday is notorious for competitive shoppers working the crowd to get the items they want, even if it takes pepper spray. But as GMA reports, it’s when public safety comes second to sales--that Black Friday gets a bad reputation.

TJ WINICK: ‘The dark-side of Black Friday was on display from Southington, Connecticut, police tasered a Wal-Mart shopper who resisted arrest after cutting ahead of 20 people in the checkout line—to Los Angeles, where authorities are looking for a woman who allegedly unleashed pepper spray on at least 10 shoppers, also competing for video games.’

MARSHAL COHEN: ‘Retailers have done a good job of taking care of the outside of the store, but they haven’t yet done everything that they can do to kind of secure the safety of the consumers inside the store during that frenzy.’

With tempting price drops and earlier hours, Sharron Lennon, a social psychology professor at the University of Delaware says there’s an explanation for consumer madness on Black Friday.

"People put a lot of effort into obtaining a promotion and then don't get the promotion, which happens a lot on Black Friday…Then they get angry about it. People are putting in all this effort getting up early, cutting out coupons ... then they get there and they find out the goods are gone…They are going to be angry, and some of them might be the ones who engage in the consumer misbehavior.”

Shoppers will be able to save their energy -- and avoid being trampled -- as Cyber Monday kicks off. Online shopping revenue is expected to hit nearly $1 billion in just 24 hours.
