Several problems of prisoners taking hostages with guns

First of all, film and television works are mostly needed by the plot;

The actual use of snipers is limited by the surrounding environment, and the angle of snipers is often greatly limited, and there are few ideal horizons. In addition, the distance of 100 meters is far away, and the shooter's level, wind and other factors will cause slight deviation. Sniper rifles are usually loaded manually. Once the first shot misses the point, think about the consequences yourself.

Finally, there is no sniper rifle in China that can shoot accurately within 100 meters.
