This could be one of the most difficult part to appropriately convey with words. There are guns everywhere, in every country. In the most peaceful places there will be some portion of cops allowed to wear guns, there will be hunters with permits etc. There will always be a non-zero chance to be shot. But whether that non-zero chance is 0.00001% or 1% makes a world of difference and will have deep impacts on how we live our life, talk to people, deal with confrontations. A low enough probability brings radical changes.
