The UNC-system Safety Task Force did well to include a recommendation for background checks in a report to be submitted to UNC-system President Molly Broad.
There's little doubt that something had to be done after the murders of two UNC-Wilmington students this year - the suspects in both of those cases lied about their criminal histories.
It would be an impossible investment of resources for admissions officials to try to investigate criminal records for all applicants to UNC-system schools, but an ongoing effort to flag indicators of potential violence is in order.
Some of the suggestions to identify trouble - triggers such as a lapse between high school graduation and submission of the college application - seem like reasonable justification for admissions officials to double-check the applicant's criminal history.
Having the UNC system go to the Department of Public Instruction, the community college system and private schools to provide it with in-state student suspension and expulsion records also seem to be reasonable measures.
