@ mufa23: That is technically brandishing xD
Anyway my dad says he doesn't like anyone knowing he's got guns, because according to him, it may possibly make some people think you're protecting something of high value. But your theory has some good ground too. I suppose by showing off the fact you've got guns just changes who might want to break into your house. It'll definitely (IMO) deter someone just looking for quick pickings, but on the other hand it may attract more experienced/hardened criminals.
None-the-less, I don't feel that showing off some guns is the best solution in keeping my computers in my possession, and it definitely won't stop the cops xD
