When is 50 a really big number?

So, today, gunmen kill over 50 in raid on town near Baghdad. Did you hear about that? Probably not, but even if you did, more than likely you just shrugged. Well, that 50 might not sound like a lot, but guess what the proportionate number of killings would be here? Iraq has a total population of about 26 million. We have a population of 296 million. So those 50 in Iraq would be about 567 people here. All killed at one time. Think about that.
