No worries, Josh. I want you to make an informed, rational decision (I am an ethicist, after all

).
I take Bullshido with a hefty grain of salt. Most of the posts nowadays seem to be from BJJ two-stripe white belts who think they can denigrate other martial artists just because they haven't "proven" themselves at the local grappling tournament.
I think the SPEAR system is really useful for dealing with a very specific aspect of hand-to-hand combat, namely the sucker-punch (or other surprise attacks) from the de-escalation stance. I believe this is consistent with Tony's overall vision: the SPEAR is meant to complement existing martial arts systems, not be a system in itself. I'm not an LEO, so I can't comment on its actual effectiveness for law-enforcement.
