The 'Food For Thought' thread prompted me to throw this one out there. I'm not a LEO, but my job puts me in a lot of similar (unpleasant) situations, so I don't post every time that I have a near-miss, as they are all too many.
However, here's a situation that caught me off-guard, even though I thought I was ready for whatever would happen;
I manage property for folks, which includes a large abandoned industrial complex. Theft has been a real problem out there, and the local Sheriff has stepped up their patrols for us. In addition, we have SOP worked out for when I find trouble while I'm checking on the property.
While driving through (behind locked gates), I see a car parked in a field with some woods surrounding it. My plan is to photograph the tags and have it towed. The field is muddy, so I can't drive in without likely getting stuck, so I walk. I have a G30 IWB and a LCP in my front pocket. As I get in range to get my camera out, I can now see around the trees to my right there is another dirt road with a truck stuck in the mud, with 3 guys working on it. As I notice this, two heads (that were not there before) pop up in the car, and two guys get out. At the same moment, one of the 3 guys working on the truck calls out 'can I help you?' (bear in mind that these guys have no business being there). Also as he calls out, two more guys come walking out of the woods next to the truck.
I now have 2 goblins directly in front of me, about 20 feet away, and 5 more about 40 feet to my right, and they want to talk.
If I approach them, I will be quickly surrounded. That isn't going to happen. Solution; take out cell phone, speed-dial Sherrif while casually waving to the nubs and saying 'no thanks - I'm good' and taking a right oblique directly into the woods. I mean I walked straight into a picker bush and didn't hesitate. Before they could react, I was buried in the woods and moving away quickly.
This entire interchange happened in likely less than 10 seconds.
I pop out on the other side of the woods and jogged to my car. 'In the car and outta there, with the cavalry meeting me at the entrance gate. A quick disclosure of my cc to the Deputy, and he and his guys were off to talk to my new trespassing friends. Unfotunately, that's all they got written up for was trespassing. However, here's a scenario where I was armed to the teeth and prepared, and still quickly put in a losing situation.
Moral of the story: Avoid it if you can (I can't - it's my yob), and get outta there if it's not playing to your advantage.
