I wonder if a muslim had killed some white kid, if the right would be defending him so vociferously.
I'll translate your post from idiot...er liberal...er never mind it's the same thing.
If it had been a Muslim who attacked a white kid, would we still want a real investigation and his only being charged if he actually did shoot a kid not threatening him? Yes, we would.
On the other hand, here's a better question. Would the left demand his arrest regardless of the evidence. No, you wouldn't.
