As a pro-violence liberal, I think that armed guards or at least the Police should be present in any major retailer during Black Friday. Sounds ridiculous but if the police are there, people sometimes think twice before doing something so stupid.
From my days in retail, some people are just animals and as a result, need to be treated as such. While I never saw anyone get trampled, the lengths and shamelessness people exhibit to get some cheap shit is disgusting. Maybe if they were starving and there were bags of grain, yeah, I could see that. For a TV? Get the fuck out of here.
