You were what some call a sitting duck. Easy to catch and good for the arrest record of the officer. It is tough to catch real bad guys, but sitting ducks do stuff without trying to hide it, in other words without criminal intent.
Sitting ducks are easy to catch cause they don't know what they are doing that is unlawful. Sitting ducks don't fight back, all too often plead guilty and again make for good numbers for the department. Some even plead guilty,are fined and later find out that the law they were charged with did not exist.
I was a cop for 12 years, when folks started talking about gun control I asked other officers in the department if they would participate in confiscation of firearms if they became illegal. Out of 79 officers, all but one said yes!
I knew I was in the wrong crowd.
