They call it “America The Beautiful.” That does not mean it is perfect.

On April 20, 1999, in Littleton, Colo., two teens began shooting inside Columbine High School, killing 13 people and wounding 20 more. At the time, it was the worst shooting in U.S. history. On Feb. 14, another massive shooting at Stoneman Douglas High School in Parkland, Fla., left 17 people dead. National Public Radio reported, “it is increasingly clear that (Nikolas) Cruz, the alleged gunman, was deeply troubled.” Social workers, law enforcement officers and others knew of his issues but never really did anything about it.

Before Sept. 11, 2001, the Oklahoma City bombing on April 19, 1995, was the worst terrorist attack in the U.S. Timothy McVeigh, an anti-government militant, and his partner Terry Nichols bombed the Alfred P. Murrah and killed 168 people. Nearly 700 others were injured.

Because of these terrible events, we really should do something about it. America is one of the countries with the most mass shootings and bombings. The public has been arguing about what we can do to prevent these occurrences from happening or at least reducing them.

It’s a dangerous world out there, but there are things we can do to make it a better and safer place.

Shootings can occur anytime, in any place. It is crucial to do everything we can to prevent these things from happening again. For example, schools or any other building’s security can be improved. There should be more detectors to every door, especially in schools. This would help the school be more aware of what could be in people’s belongings.

In the event that there was an armed person walking about, there should be more secure areas. For instance, the walls and doors could be bulletproof. Doors should also have a two-way lock, instead of having to open a door to lock it. You will already be inside the room while locking it. Another improvement we can do is to practice drills in the event of an armed person.

We might not make America perfect, but we can make it better.
