Video isn't as good as hands on-if the hands on instructor is competent. John Farnams defense-training.com has videos you can watch for a fee. Mas Ayoob's Ayoob Group has a class schedule, there might be a class near you and he does cover after-the-incident issues.

You might want to check on copies of Mas's books on legal issues. The most recent is available through Amazon.

I'm certified as a civilian instructor, was a LE instructor. Bear in mind that an instructor who is trying to sell you the one true way is dangerous. Instructors will differ somewhat on material, keep your male bovine excrement detector working. I've never agreed with 100% of what any of the folks I was trained by presented in over 30 years.

My issue with the NRA requirements for the legal issues is that use of force law is a specialist legal practice. Your average attorney is going to cover their butt. Some LEOs aren't much better. I can document over 100 hours training in this area and I've heard some stuff presented as fact that's just inexcusable.
