Cars, toasters, "various household products in the right quantities" and more. All been used as weapons.
Let's start with the really dangerous stuff first. Let's undo the bans on all illegal recreational drugs, guns and so on... then start at the top and ban stairs, cars, fish with bones in and the other really big killers... then we'll move onto banning the less dangerous stuff like screwdrivers and kitchen devils - eventually we will be able to ban the least dangerous things like guns and other knives.
Then we'll move onto blunt objects and eventually regress to some wierd animalistic state where we catch prey bare handed and eat it live and raw.
Tools are ALL dangerous - no exceptions.
Ban it all - give us a government operative in each house to cut everything we need - put us all on public transport and we'll go down to the rec for social time.
Welcome to Airstrip One folks.
