To Whom It May Concern,

I fully understand your concerns about the safty on Campus in the United States.

The arm abuse in the United States is a serious social problem. It bothers everybody from campuses to homes in the States.

As you know, free bear arm is written in the American constitution, which is no way to amend in next couple of years.

So far, nobody can ensure your security in terms of campus shooting. However, the shooting definitely is a low possibility event in terms of mathematics. And I encourage you to do more research on this issue and make a decision based on your understanding about this demerit of America.

Regards,

Jiayu
