I'm not a fan of Suarez. First he was convicted of defrauding the State of CA for disability pay he was taking while he was out running around doing his fancy tactical spetsnaz rolls. Second, it seems everything he writes includes ad hominems and childish insults about anyone that doesn't agree with exactly how he does things. Third, anyone who talks about how lucky he is to have had the opportunity to kill other people has some issues. Fourth, anyone who routinely brags about having killed people as cop likely has some issues. Fifth, he will write and talk like the way he does things is unquestionably the best, put down, and react very childishly to anyone who suggest otherwise and then later adopts their ideas and even try to claim they are his own. An example of this were the articles he wrote about modifying AKs and trying to make them into ARs and now look at the TSD AK he is selling. I remember when he and his minions were bashing anyone that would put an AR stock on an AK now it is the greatest thing since sliced bread. Sixth, I've seen him flip flop on his reviews of enough products over the years that his opinion means a lot less to me than it might otherwise. Seventh mush of his marketing is in essence geared towards mall ninja red dawn fantasy stuff (ex. being a guerrilla sniper out operating on your own) even if the base material is good.
Much of the above is made even more amusing by how "insistent" (for lack of better word) he is about being a good Christian.
Just based on his articles and internet posts I don't think I could stand to be around him. Even if his training was something special (and I am far from convinced that it is any better than what can be had elsewhere) he is dishonest, brash, and very arrogant. In sum, there are other people I would rather train with.
