>Own a musket for home defense, since that's what the founding fathers intended
>Four ruffians break into my house
>"What the devil?" As I grab my powdered wig and Kentucky rifle
>Blow a golf ball sized hole through the first man, he's dead on the spot
>Draw my pistol on the second man, miss him entirely because it's smoothbore and nails the neighbors dog
>I have to resort to the cannon mounted at the top of the stairs loaded with grape shot
>"Tally ho lads!"
>The grape shot shreds two men in the blast, the sound and extra shrapnel set off car alarms
>Fix bayonet and charge the last terrified rapscallion
>Bleeds out waiting on the police to arrive since triangular bayonet wounds are impossible to stitch up
>Just as the founding fathers intended
