Maybe you're too young to remember the time when poor violent neighborhoods protested local public services and the federal government for refusing to serve their neighborhoods. Racism was the rallying cry back then, and it's still the rallying cry now that police serve once-neglected areas.
Democrats are just expressing outrage that their bullsh*t policies don't fix anything. Poor people are still poor and helpless, and the lower-middle class ladder out of poverty is blown to hell. Naturally, Dems issue more food stamps, Medicaid, and unemployment checks. Then they start trolling Republicans until they find someone to take the bait.
It's a brilliant strategy, as long as you have an appetite for needless human suffering. Do you think Landslide or Lief know anything about fixing poverty or violent crime? Do you think they care as long as they can buy a constituency and indoctrinate them to a certain world view?
