The lawyer time I mentioned helps Charlie to know how to protect his future if there is any possibility that there may be long term physical issues. This is potentially more than just immediate out of pocket expense, possible future issues as I mentioned, missed wages, etc. I'm not sue happy, but I think a little up front expert advice is a good thing. The "friend's" insurance company is not Charlie's advocate / friend / on his side. They work for their shareholders. My experience (2x) for similar (injury not gunshot though) is the insurance companies are difficult until it looks like it will go to litigation. I haven't sued, but it took a long time and threat of litigation to get them to do the right thing. I may be biased and that may not be the norm, but it my experience. I would pay up front a couple of hundred for advice.
If no personal injury is involved in an incident, property damage only, I'd probably wouldn't get the paid advice. Moderate to serious personal injury, yes! Is a risk/reward decision, different for each of us.
