The New Orleans Police Department, reacting to a joint investigation by WWL-TV and The New Orleans Advocate, is trying to limit the number of crimes erroneously listed as "unfounded" calls by officers.

"Now, we're implementing a protocol for supervisory approval for all unfounded calls," NOPD Superintendent Michael Harrison said in a City Council meeting last week. "Someone, whether it's in communications or at the district level has to contact that complainant to ascertain if a crime was committed and if it was, we're going to dispatch to it and amke sure we capture that."

Prior to the new policy NOPD officers would often arrive at scenes hours late to find victims long gone and, in many instances, then mark the crimes “unfounded” — meaning that in the department’s view, they never occurred at all.
