In Brazil the punishment for murder is lesser than many other crimes, leading to people murdering investigators (or in one particularly infamous case, a mayor murdered two environmental cops that were going to investigate his farm, got convicted, but still got re-elected).<p>Also firing a gun and not hitting anything also has a harsher punishment than hitting someone, so unless you are a cop that need to draw attention or something, if you need to fire a gun, you need to make sure you will hit someone.
