"A fair bit" isn't particularly precise but it does means "quite alot" or "a large amount" so think it is a gross mischaracterization to call it a gross mischaracterization. If we are being pedantic, "Several times" is more accurate than "many times" since many generally means a bit more than 4 or 5.

I don't think so. Practically speaking, all that matters is comparing absolute risks of different causes of death in a specific situatio. For a foreign tourist the risk of gun related homicide in the US is significantly smaller than the other risks of death (such as cars). The relative amount of that risk compared to other countries isn't practically relevant. The risk of drowning in a locked dry room is many times the risk of drowning in a bathtub with an inch of water, that doesn't mean that the risk of drowning in that bathtub is practically relevant (unless you are a baby or extremely drunk/drugged).
While not exactly wrong I would definitely argue that "a fair bit higher" is a gross mischaracterization. The US has an intentional homicide rate of 5.3 per 100,000, which is many times higher than UK (1.2), France (1.3), Germany (1.0), Spain (0.7), Italy (0.67) or any of the Nordic countries.
> Concerns about gun policy (and the death penalty) by potential visitors to the US are thus ideologically, not practically based.
Depends how you frame it. Yes, your chances of getting killed in a random shooting are lower than a lot of other more mundane things. At the same time, your chances of getting killed in a random shooting in the US are many, many times higher than getting killed in a random shooting in one of the European countries previously mentioned.
