Encryption
Yes, I believe some agencies have unwarranted use of encryption. Some officers seem to understand the hobby while others don't.
Here is what I get when I am stopped by LE agencies. Generally speaking, the first thing out of their mouths is, "were you listening to me?"
I had one odd officer who thought I was training binoculars on IH35 & reporting such on the CB. What a weird situation that turned out to be. As I have stated many times, I told him you must have been talking about the leather case on my scanner.
When you have an agency enabled in your radio, and you are stopped, what are you doing to do? If they ask for you to turn it on, like several have done, they are going to hear their radio traffic on your radio.
Many officers don't understand how most people scan, for anything that moves in the general area. Ha.
Since I don't have anything to hide, they can waste their resources if they like.
In my opinion, Homeland Insecurity has elicited a hyper-alert level that does not apply to most citizens. I think some LE agencies are losing sight of this. Well, that is my opinion.
