as a police captain who has instructed criminal justice students at the master’s level for the past 5 years, i often hear the same questions in training, at conferences, and around the station. i will recommend her to anyone who asks. most awful of all, leaking gut can be quiet and reveal no signs in the beginning. i don't think most 'experts' are ready to take the next step. we had 2 hot sunny days, the rest was rain/then clear in the late afternoon. not really the sound that i expected. thankfully, i placed it in just the right spot to benefit from the slope.
