I agree with Flying Binghi, anything could happen, absolutely anything, can't trust them terrorists...
Therefore Binghi my mate, replace that wooden rear door of yours with a reinforced steel door, weld the shutters over the windows, replace the insulation in your roof with Aluminium foil (no gaps!), pour some David Gray's Dusting Sulphur into a tin can and wire it up with a flash cube to the security light over your front door, sandbag the perimeter of your property and put two rows of Cat 3 wire in the frontyard channelling into the porch where you can sit with your pump-action on a rocking chair and listen to your Chiuaua take on the world as it passes by...
