As a veteran I heartily agree, but it shouldn’t be limited to personal weapons. Here’s some examples to avoid.
1. Land mines, if you don’t chart properly where you place them they can really ruin a backyard barbecue.
2. Razor sharp concertina wire, should never be liberally spread around the inside of your home. I trust this is self explanatory.
3. Fragmentation grenades attached to a door handle, makes you stop and think when someone says “Come in the doors not locked”.
4. Electric Shock door bells, especially when incorrectly wired to the local power grid.
