What caused the downfall of the Black Panthers group?

My dude you really need to study history a bit. Things people did in the name of profits:

*locked emergency exits so that workers cant sneak out resulting in many deaths in fires

*continued to sell cars they knew were dangerous and killed people because the potential fines were cheaper

*pollute rivers until they caught fire in some areas

*essentially used the US government as a bludgeoning weapon to topple south american governments over concerns that said governments might threaten their banana profits

*added melamine into dog food because it caused protein content tests to falsely show higher protein content resulting in many dead dogs

*sell the methanol containing heads of distilled spirits which can cause injury or death

*700,000 deaths a year from smoking related cancers and other associated diseases whoch the tobacco industry fought tooth and nail to dismiss links between said diseases and smoking

*entice women in africa to forgo breast feeding in favor of infant formulas often made with contaminated local water which didn't just harm their children but also ensured that they became completely dependant on infant formula once their milk stopped coming in.

*the modern fossil fuel industry is responsible for climate change and theyve known this since the 70s according to their own leaked internal documents. similarly to the tobacco industry theyve been spreading misinformation for decades trying to stop anyone from regulating them. this is very likely to substantially compromise global ecosystems, increase resource competition and subsequent conflict and make much of the earth effectively uninhabitable.

I dislike how this comment is deliberately vague as to who you're talking about.

I'm not sure if you're talking about these specific communities, or all of America all of the time.

Yeah, it's definitely the fault of the poor folks.
