Well, no. My hearing isn't good over the phone, so I tend to go over first and call later. People have different styles. That doesn't make them sinister.
LE is not always nice. We tend to see their good side because we see them working on the most difficult cases, but there's plenty of abuse of power and just plain stupidity out there. I was a single mother at the time. Had to call to report that the neighbor's house was being broken into. They came to my house, not the neighbor's, and gave me a third degree about why I didn't have a husband and how was I taking care of my daughter. I really thought they were going to arrest me and take my daughter to child services, and as far as I know they didn't do anything about the neighbor's house until the neighbor got home from work and called several hours later. And I have no idea how they knew I was a single mother.
