Personally after seeing well trained guard dogs, I'd not jump the fence no matter how many guns I was packing. Painful way to go being torn up alive and eaten up by purposely slightly under fed k-9's. Crooks generally want easy pickings, one rule on security is making your car harder to break into than the ones parked either side of you, having better security than your neighbour etc. I like the black powder idea though......just as he puts his feet up after loading the stove with stolen wood... BOOM surprise!!
