I’m just relying to what was stated above.
If the approaching crowd isn’t using hands and feet you’re not going to be harmed.
Never in my entire life have I heard of or seen an attack where a crowd of attackers simply closed in on someone and sat or laid on them. At a minimum someone is going to have to either hit you, kick you, or wrestle you to the ground in such an attack.
Simply being surrounded is not going to be justification for the use of deadly force in most jurisdictions even if the crowd is verbally abusive.
There must be an actual imminent threat of grave bodily harm or death before we can use deadly force lawfully.
