I have no actual "badge number." I have an ID number, but it no where visible on me. I have a name tag anyone can come up a look at (at least I do when I wear a uniform--not often anymore).
I read about people thinking there are better uses of resources than issuing tickets. Another thread (that was closed) that was more anti-law enforcement than this one suggested we focus our energy on "real criminals." Believe me, we have people that focus on every type of crime you can think of. Violent Crimes Unit Detectives work Violent Crimes, Vice guys work narcotics and undercover stuff, my current unit forcuses on burglaries and other property crimes, Traffic guys pay attention to (guess what) Traffic. So if you see a bunch of cops working a DUI checkpoint or something, it is not like the other things are being ignored--these are just the traffic unit guys.
No one likes a traffic cop. It's not really fun to be one. When you become one, you end up basically dealing with good people who drove too fast. Who among us has not? This may be the only contact they've ever had with the law. But on the flip side, the threat of a ticket is the only reason people don't break more traffic laws. Imagine the chaos if there was NO chance of a ticket for anyone.
And a little on Radar and Laser units. Scanning a radar against a wall will induce a false reading, that's why you are trained (you have to take a course and get certified) not to do things like that. A radar unit will NOT distinguish between two cars--even if you mount a red dot sight on it. A LASER unit will. A Kustom Pro 3 laser has a heads up display--kind of like a C-more sight--so you can single out an individual car from a pack.
