When I took my class I did think one of the student might have been law enforcement, interesting to read that people say the NSP does go in and audit classes, makes me feel a little better about my eye! I was a paramedic and in that job I met several LEOs and this guy just felt like he was a cop.
my input on this isn't even worth my $00.02 but to me it comes down to integrity, if the teacher is who he says he is and is knows what he says he knows students will have a good class and will learn and more students will go.
$50 or $200 doesn't matter in things like this, where most of the students are professional conservative people, money isn't a huge issue when it comes to proper training, however integrity is.
