I really haven't really heard anyone, even protestors, claim that police in the US should give up their guns. The recent high profile cases of deaths haven't been by gun, but with bare hands. Mostly, the discussion is around if/when deadly force should be used, no matter the implement.
That doesn't mean there won't be police. Other cities have disbanded their police departments. All have been replaced with a new police department. The idea is to replace a poorly run department when reform isn't good enough. The idea isn't to have a completely unpoliced city.
Camden City PD was disbanded to reduce the costs of salaries and benefits with new union contracts. The CNN article doesn't even contain the word 'union'.
That's beside the point. My reason for linking the example was to illustrate that departments have been disbanded before and it's a more aggressive strategy for change than attempting to reform an existing department, not a call for lawlessness.
"disband the police" fits on a sign, but it's an incomplete statement.
I agree with that impression, and actually find it really puzzling that disarming police isn't a central message. I think it's very likely that if the police on George Floyd had been unarmed that eventually the bystanders would have intervened (at least I hope).
