Is this song about the shooting - by police - of Trayvon Martin? Or one of the other shootings that sparked the Ferguson unrest?
Or is it about Freddie Gray? That's who came to mind when I heard it.
I took the song to be about a mother losing her son in a terrorist attack but that's because I initially thought Neil was saying "The Lord Is Always On Your Side" ... so I took it to be about a mother losing her faith and having to grapple with how God can let such horrific things happen.
Personally I don't believe it's an accurate portrayal of the Ferguson case. The song is trendy and topical certainly.
