I have much mixed emotion about content. As everyone knows I am pro law enforcement for the use of dogs. Am still a consultant for two depts.
But let me tell a little story about an experience when I was in military. At that time I was handling a Narcotic Contraband Dog. We used to run missions on post where we might run 100 cars in two hour period at certain junctions. Now I had the top dog on the post in terms of "finds" and in terms of % of finds. My dog worked at plus 95% well into over a hundred finds.(I even got a commendation from Dept. of Army on his working results).
We were working an intersection one night and a van with long hairs came through the roadblock. Now we had unwritten orders that if a Van with long hairs, or Blacks, or a luxury car with young blacks in it, the dog WILL alert. Now I was the only African American in the Narcotic dog unit. So on this night a van with long hairs comes through the roadblock and I work Gustav on the vehicle. He did not alert. I purposely took him around the vehicle again....still no alert....so I told the driver he could go. The OIC went bonkers and asked me what I was doing....I told him the dog didn't alert.....he told me to put my dog up and I was through for the night.....I had just started....lol. Anyway, the next day I was called in and questioned about being a team player.....I told them I had the best d--- dog in the unit and if he didn't alert...then I saw no need to call one. Needless to say this didn't go over well, but they couldn't discipline me because they were wrong!
So I really see both sides of this coin....lived it! Any of the handler with the passive sit alert dogs could make their dogs false alert anytime they wanted, so it is not improbable at all. I am one that believes if we as law enforcers cheat at enforcing the law then we are no better than the ones we seek.jmo
