They didn't make a false report on purpose. And their police mostly don't kill people.
Last time I checked the stats the per capita (%) US rate of gun deaths from police shootings alone was higher than the entire gun homicide rate for Europe.
Making a false report is only a bad thing if they did it maliciously. I'm assuming they did it out of naivety rather than out of malice. In the UK the police are less inclined to kill people for no reason (of course, it does happen but it's way less likely).
