What does safety mean to you?
A campus where most crime is student against student (theft, sexual assault); a campus in an urban area where you should take the campus run safety vans or call for campus security to walk you back from the library at midnight; a campus where students frequently get sent to a local hospital with alcohol poisoning; a campus where the administration is scrupulously honest about reporting incidents so students can be aware or a campus where the administration fudges the numbers, sweeps incidents under the rug, try to pressure students into not pressing charges?
Figure out what YOU mean when you say safe- and then do the research.
