I'd heard rumors about Kaiser's DUI, but that was before my time. I also had heard rumors about him getting friendly with the CSS and Intel Airmen when they were deployed circa 2003, but never proven. I know he blacklisted some Herk guys from the 89th when he was the recruiting officer. I'm friends with his Load Superintendent and he has nothing but positive praise for Kaiser, and he was stationed with him before. So YMMV.
He's no saint, but neither is Rat (considering his old Sq failed an ASEV right after he PCS'd unscathed), but Rat is connected and in the driver's seat. I saw him do shady shit as well to people's lives so I'm not surprised about all of this.
