This time I was not the primary object of their attention.
I was driving back from the range when the van ahead of me displayed about 15 miles' worth of aggressive & potentially impaired driving. So I called 911.
(Extreme tailgating - 1/2 car length @ 55mph - & weaving from the center line to the gravel, over & over & over, very regular & deliberate. She tried to tell the cops that she was trying to pass... I'm not believing it 'cause she could see the cars stacked up ahead of her & she could see oncoming traffic. She was driving a van!)
Just as I was turning onto the ramp getting on 45S, a squad came flying up behind/around me & pulled the van over at the bottom of the ramp. I stopped 100yd or so back, as the dispatcher said to do.
Another officer stopped behind me, with a deputy behind him. They came up & talked to me, asked for my info, & in providing it I mentioned "not that it really matters, but I am armed".
(The deputy - on the passenger side - had already figured that out. Helps to actually look...)
The officer might also have seen my carry license, since it's with my driver's license.
Absolutely no reaction that I could see, from either one.
I explained what I'd seen, then those 2 went up to join the 2 already at the van.
The 4 officers had a Chat [TM] with the driver (female, professional delivery driver for a map company) & told her in no uncertain terms that she'd better clean up her act. Apparently by the time they were through she was quite clear on the concept of continued bad acts = possible loss of job. She didn't get a ticket, so I don't have to mess with going back up there to testify.
LOL... they asked if I wanted to talk to her, & I said I'm pretty sure they'd already covered everything I'd want to say, which amounted to "stop driving like an idiot".
