Get your legal advice from a real lawyer.
Good idea. And if you are having a trust created, there's a specialist for that. For bankruptcy, there's another. For tax affairs, another. Divorce--and so on. And then there are criminal lawyers....
Get your gunfighting advice from somebody who's actually been in a gunfight...
Well, that's kind of like saying, "get your air combat training from someone who has actually engaged in real air combat". Problem is, there are fewer than a handful of such persons left in the whole world, and they are probably fishing, or running some company.
So, today you get your training in simulation and in flight exercises designed from real world experience, and enhanced by analytical evaluation of newer technology that didn't exist when the aces of old ruled the skies. And the instructors are rarely pilots with real kills to their names.
Same thing when it comes to self defense or law enforcement or security training at Gunsite, LFI, SIG Sauer Academy, and so on. They teach what works, constantly updated, but that doesn't mean the instructors have ever shot anyone.
"Gunfighting" advice? All I really need is SD advice. A Marine or SOCOM fighter needs a lot more.
...or at least worked a real l.e. or military job.
Real LE job? That would include Massad Ayoob. Includes a policeman I talk to all the time. Doesn't mean that I would consult a couple of other police officers I know for any kind of "gunfighting" advice.
Real military job? I would listen to an expert before listening to someone who carries an M9 with FMJ rounds in the magazine and none in the camber.
Speaking of experts, if your case is less than straightforward, your criminal attorney will probably bring one in to explain to the jury the way lethal force incidents unfold within the constructs of the law and to counter the arguments of the prosecution.
He probably should employ one who is highly experienced in such testimony. He might even be able to retain a former Vice Chairman of the Forensic Evidence Committee of the National Association of Criminal Defense Lawyers (NACDL). Might even be the person who developed a course for attorneys entitled "The Management of the Lethal Force/Deadly Weapons Case" which Jeffrey Weiner, former President of National Association of Criminal Defense Lawyers, described as "the best course for everything you need to know but are never taught in law school."
That would be Massad Ayoob.
Yes, your "real lawyer" may need some expert assistance. If he does and does not recognize it, you have not chosen a very good one.
