There will be a well proportioned response, but it won’t be an actual SWAT team. There’s typically one such team per five to ten million people and they won’t move for a joke call.

But more importantly, with an order of magnitude rarer killings, there is much less of a “we’re at war with the bad guys” culture. In some countries discharging a weapon brings automatic suspension for the investigation, even if nobody gets hurt. Cops simply don’t tend get trigger happy in this environment.
