No the abused should call the police
If you not gonna get your abuser arrested then you shouldn’t expect random people step in and do anything
I’ve seen situations go bad for people who try to step in other peoples domestic situations
One of my friends growing up got stabbed up and almost died because he put hands on a dude that was beating his girl up on the bus stop
and the girl who he was trying to help ran away with her boyfriend and left my homie to die laying on the curb bleeding out
Im never blaming any nikka for minding his business
9 times outside 10 she gonna still be with the nikka anyway
It's not that easy. A lot of times the abused know the police aren't gonna do enough to protect them. The abuser gets thrown in jail for a night or two, and then what? Especially when the abusers are police which happens a lot.
