3. 911 tapes.

There is no authority with respect to 911 tapes per se. However, radio logs are generally subject to inspection. 67 Wis. Op. Att'y Gen. 12 (Jan. 25, 1978). Requests seeking copies of 911 tapes, like all other requests, must be reasonably limited and defined. See Schopper v. Gehring, 210 Wis. 2d 208, 213, 565 N.W.2d 187, 189-90 (Ct. App. 1997) ("We agree that to require a custodian of a record to engage in the copying 180 hours of tape and the creation of a log to identify the time and the order in which the transmissions were received represent a burden far beyond that which may reasonably be required of a custodian of a public record. '[A] request for a record without a reasonable limitation as to subject matter or length of time represented by the record does not constitute a sufficient request.'").
