Good question – although I have an affinity for weaponry in general, in this instance I thought to myself, what would Jesus do? Jesus is my gardener, and he graduated from the University of Bogotá with a first in International Law & Politics. After a detailed chat he related to me a parable that might help answer your question.
There was once a druglord called Romario*. Romario was a decent enough gangster – he didn’t try and take over the turf of others even though he occasionally had the odd bust-up. But Romario had problems. In a nearby neighbourhood was another gangster called Jose. Jose and Romario had a long standing grudge and were sworn enemies. Romario had good reason to believe that Jose had managed to get his hands on a couple of Saab AT4 MKII anti tank rocket

launchers, which could cause big holes to appear in Romario’s house. On top of that another druglord, Big Stevie had just muscled into two neighbourhoods right next to Romario’s and he had an alliance with Jose. So Romario was in a tight spot. What was he to do? Things looked bad all right – Jose and Big Stevie might try and take him out at any time – Big Stevie in particular had a long track record of taking over enemies turf.. So Romario sneaked out one night and stole some rocket launchers of his own and blew up Jose and Big Stevie, triggering a huge gang war in which everyone died. The end.
Hope that helps.
