Guns are a problem all across the USA, not just Cleveland but I think other campuses like GaTech are about
the same or a little worse than CWRU for safety. Cambridge MA had one murder per month when I lived there
on Memorial Drive, in early 1980s, the road where all the MIT dorms are. Staying indoors after midnight is a good rule in Boston, the area around Columbia U, U of Chicago, U of Southern Cal, in Los Angeles and JHU, as well as CWRU.
Parents who are really nervous about crime at colleges, should look up the death rate due to drinking, drug use, suicide and car accidents and they MIGHT feel better. 
Statistically speaking its very unlikely for a college student to die of gun murder. Even School shootings are very rare, and thats not typically East Cleveland gangs
but crazy students shooting other students. So again, your child is not likely to get shot, its just a very low probability.
Here is a recent crime map of East Cleveland and you can see where 55th is on the other side,
but again, CWRU students don’t have to walk into East Cleveland and they do not do that.
They can occasionally shop over
there without a problem, using a car. I have done that.
I think it requires a visit to really understand the layout there, and the
train line divides up this area. So students are walking the other direction towards Cleveland Clinic and Art Museum,
or taking a bus into downtown but rarely going into East Cleveland as downtown, the international airport, the West
side market, students are traveling west to get to those.
I would suggest students visit, maybe with their parents , use the trains and busses and decide if they are comfortable living in Cleveland.
Take the Healthline Bus that runs up and down Euclid and into East Cleveland,
to the lake front and see if you can handle it. You will be riding this bus with East Cleveland residents
and I have never had a problem on the Healthline bus. Many East Cleveland residents work at Cleveland
Clinic, and get off there. Downtown Cleveland is about 15 minutes to the west on the Healthline bus.
Case students get free transportation and learn how to use it.
I road the trains and busses in the winter
in Cleveland with my son five years ago in Cleveland and decided he could handle it.
Cleveland is a caring community. My son enjoyed tutoring middle schools students from East Cleveland
who came into University Circle for a math program at a church on Euclid. It was safe to walk
to that church and safe to work with these students.
