Could not agree more. I think a lot of instructors use Rescue as a "hazing" more so than an actual teaching class. Same thing happened when I went through the academy. We had "volunteers" that were playing the role of suspects in various scenarios. These volunteers who pull out grenades during a traffic stop. I mean seriously is it possible someone could have a grenade, sure, but it would be the 1 in 89264298765298475628937562987 type situation. Train for the common, but make the student aware of some of the uncommon possibilities.
