In 2006, in cases where police officers intentionally fired a gun at a person, they discharged 364 bullets and hit their target 103 times, for a hit rate of 28.3 percent, according to the departmentâs Firearms Discharge Report. The police shot and killed 13 people last year. In 2005, officers fired 472 times in the same circumstances, hitting their mark 82 times, for a 17.4 percent hit rate. They shot and killed nine people that year.
I believe it is right that police officers should be allowed to carry a firearm, or else, our entire country would be overrun by crime and murder. Today, more criminals are armed and dangerous. It is the police officer's job to keep them off the streets, and to protect and serve citizens from harm.f a cop is trying to arrest a serial killer, and the serial killer has a gun, all he has to do pull a gun on the officer and the police officer canât do anything about it because he doesnât have a gun to defend himself with. Police officers need guns to help them arrest criminals and give them a distinct advantage.
