Man kills a teenager for making noise

People are on a much shorter fuse nowadays, with the patience level having drastically reduced. And with the easy availability of weapons, the chance of this rage translating into something deadly has increased drastically. Consider this case where an elderly French man fired on a group of teenagers who were making a lot of noise (maybe too much noise for the gentleman) who killed one of them. The gunman was eventually caught by police (link to article):

Police said the man started shooting at “a group of teenagers who were talking loudly” in the eastern village of Guemar at around 1:00 am (2300 GMT Thursday) before taking refuge in his house. One of the youths who spoke to him was shot three times and later died from a wound to his shoulder, said police.
