shen in the uk and aus our law makers deem anything that looks like a weapon to be treated as one

Story;
grandad drops the kids of home goes to shops for a paper (one of the grand kids leaves his "toy"gun on the back seat of the car)
granddad doesn't see it someone else does phones the authority and SO19 (SWAT) swoop down and drop the old guy on the floor and arrest him then realise it's a toy and do him (granddad) for waisting police time

this is the extent and worst case ive heard of over in england but a little while ago some 7yr olds where arrested for playing outside with BB guns

mad world
