I agree- if I’m a terrorist and I can’t hijack a plane since the cockpit door is locked during flight (and bulletproof I believe), next best thing is probably “bomb in airport”. Why kill 100 people when you can kill or injure 1000? But of course you can do that without going through TSA. In that sense, as an airport patron, I’d rather have more bomb-sniffing dogs and armed police than TSA “agents” and cavity searches.

Also, why is it up to the airline to tell TSA whether I am enrolled in PreCheck or not? If it’s not on my boarding pass, I must not have PreCheck, huh? Department of Homeland Security isn’t really sure whether I have PreCheck or not.
