Yes, pointing little holes in the air can kill people!
There are many shocking cases of people who have died trying breath through 'airless' holes caused by others who have pointed in their direction. In most cases the people doing the finger pointing have no idea of the danger they are putting others in. Children must be cautioned by their parents constantly.
There was however a notorious case in south Estonia in 1979 in which three men wanted on suspicion of money laundering escaped from police custody on their way to their committal hearing. It is alleged the three prisoners pointed so many times toward the front of the van it caused the driver and his companion to asphyxiate. The vehicle crashed and all three prisoners fled. To this day they remain at large.
