Why is everyone jumping to conclusions? This probably has nothing to do with Islamic terror, it's simply a neighborhood Sharia group enforcing anti-alcohol laws in their neighborhood...
Being from Sacramento, EVERYONE knows that area; it's referred to as "Lavender Heights". It's where all the gay bars are. That's not to say the guy is gay, lots of straight couples go there because the gay bars are the best dance clubs in downtown Sac. It's reported he was with another guy, and 3 girls. And it's not an area unknown to violence of this type. When I was a medic, I ran a good number of calls there and it wasn't even in my district.
