I have taken LFI-1 and am slated to take LFI-II this summer. I wrote a review of LFI-1 that was published in Women & Guns this past January.
My thoughts about Mas Ayoob? First off, on a personal level: he's a nice guy, but a study in contradictions. An avowed feminist (yes, really), one of his more popular books (Stressfire) contains some decidedly out of date opinions about female capabilities. (Glad he's since updated that set of opinions anyway!) A man of strong professional opinions, in person he is surprisingly easy to engage and is very open to evidence proving the opposite of his expressed opinion.
His resume is impressive. Not just the sheer volume of his work, but the breadth of it, is surprising. His professional associations and recognitions are certainly convincing -- but more convincing is listening to him talk on legal issues related to use of force. He doesn't just give opinions, he follows those opinions with legal cites, anecdotes, references and citations to back his opinions up. And the citations are obviously right at the tip of his tongue. Whether you agree with him or not, Ayoob knows his stuff.
His language is foul, shocking, annoying, and completely unnecessary. Yeah, I know he does it for a reason, but in my opinion the reason is poorly thought out -- but I will add that he puts on a heckuva show and that the language, disgusting though it is, is one way of keeping people awake for long hours listening to lectures on a grim subject.
His jokes are equally as offensive as his language. Perhaps the most annoying drawback of listening to the lectures in LFI-1 is that they were liberally spiced with the same ain't-sex-funny joke, over and over and over again. Yeah, sex is funny. And you could tell he'd put a lot of thought into mixing the jokes up, equally offending (in no particular order) lawyers, policemen, ordinary citizens, homosexuals, straights, whites, blacks, asians, women -- you name the group, he's got a joke to offend them. I asked him about it after class and his comment was classic Ayoob, something along the lines of, "I cannot avoid offending some people, so I try to make sure everyone is equally offended. It's kind of a PC thing." (That quote is NOT verbatim, but is the gist of what he said.) All very well and good, but you know what? No matter what joke he was telling, his punch line was sex in one flavor or another. It got wearying.
But grumbles about his style are really beside the point.
When Ayoob expresses an opinion, I may not always believe it but I always take it seriously. He knows what he's talking about, more often than not.
