Err, that's a nice little quip but that bit about shooting isn't even remotely close to reality.
Example: There's about 80,000 - 100,000 gun related injuries in the USA per year. That's about 250 people getting shot each day. However, we are working against a population of ~330,000,000 in the USA. If you take the 100,000 / 333,000,000 = 0.0003. That's 0.0003 per year per person. So the chance of a person getting shot in a year in the USA is about 1 in 3,330.
To look at this in another way, the fellow said there's a group of 400 people and 1 is shot each day. That means in 1 year, nearly everyone in the room would have been shot, and in 2 years some people would be shot twice.
Look, the USA is pretty disgusting with some issues, but if you want to throw numbers around, at least make them accurate, otherwise it undermines the whole argument.
