Firearms are used for several reasons
-Cheating in a
knife fight
-Commiting Crimes
-Hunting
-Destroying small objects out of boredom
-Target Practice
These tools first came around in China with the work of
gunpowder. Europe began using firearms in the late 1300s. In the 1500s, the arquebus arrived and anyone could be recruited into the army in a short time, thus knights or any other honorary soldier that had spent a years to a lifetime training weren't needed as little skill was involved in operating a gun. In modern times, many countries have banned them, but they remain common in criminal hands. Although most firearm owners are honest non-criminals, any idiotic scum can get their hands on a firearm, giving it a bad reputation, and giving politicians thought about banning specific guns. There is much controversy in this issue,
afterall some people just like going
duck hunting with 155mm howitzers, and small concealable
silenced automatic weapons designed for murder are perfectly safe after all.
