"Low or high. Makes no odds "
Probablities make no odds ? Odd.
You presumably condemn the recent anti war march in London, which could easily have delayed ambulances and cost lives.
You presumably believe the Fire services shouldn't be allowed to strike, to avoid punishing the vunerable and risking innocent lives.
You presumably never get in a car in case you knock someone down.
All actions have possible consequences but in action isn't an option.
