I wouldn't be able to find a link, but I recall a Travel StackExchange question a couple years back where a European was asking how to stay safe from gun violence during their vacation to the US. They were terrified they might be randomly shot by a stranger, or pulled over and shot by the police.

Obviously this view of the US is deeply misguided - but this is the problem our sensational media creates. It makes rare events seems commonplace and irrationally freaks people out.
