I would agree with you about the CCL but we are discussing an advanced course in handling a shooter in a school. There are some situations that applicants should be trained for and its even possible that the training will show some people who are not ready to accept this responsibility.
If you are going to require extra training, then the participants deserve to be paid for same.
You’re right, I forgot about the specialized training. Around here, the local counties take turns teaching Active Shooter classes...that anyone with a CPL can take. And yes, I agree it would be nice to be paid for the day and the ammo!
