I just had a long conversation with fire marshal who has huge experience in hardening homes. 

1. The Fire Departments are riddled with DEI. Fortunately this doesn't impact firefighters. If not qualified, too small, they end up with jobs that don't put other firefighters at risk. 

2. However, the road to advancement is closed to those who don't meet the right criteria as to race, sex, gender. So, as you may have noticed, the management all fit the bill. 

3. Pretty much everything that has been part of the analysis I've done on this thread and everything on the attached video are 100% accurate. But I did learn some new things, which I'll share on other posts.
