There are far more than one or two people in the world who can pull off the techniques live, that's more fud. Most police defensive tactics courses at a local and national level rely equally on Aikido, Judo and BJJ. I've seen plenty of other officers make this stuff work and you have had two LEO's here tell you the same. We've linked the videos back and forth, Rokas even changed his opinion to the fact that its a training issue. We can argue over how practical or effective something is or why you might want to use an aikido technique over something else, but its the same subjectivism we have been going round and round about.
Pain compliance, controlled throws and locks, less lethal force is a good tool to have in the toolkit. You want to spend the least amount of time training to learn how to fight? Not Aikido's thing, worst choice you could make. Want to learn how to protect yourself and maybe not hurt the guy trying to hurt you? Now we walk into the realm of where Aikido has something to offer. The bokken techniques were adapted from bayonet fighting and they work for weapon retention techniques, so they get used by the military. The chances of you getting rushed by a drunk, ESPECIALLY as a bouncer is much likelier than you having to go three rounds in the octagon as someone who doesn't compete. Aikido may be a terrible choice to fight off a pack of ninjas but thankfully, most of us will never have to do that. Punch a guy, even as a bouncer defending yourself and the guy falls and cracks his skull, you are going to jail. I know its easy to dismiss, but there's reasons for it, maybe not for you, but I'm very happy with the time and energy put into it and out of everything I have trained, I have used the Aikido and Judo by far more than anything else.
