I have flown recently with Mag AA with nothing except a smile from the TSA. I have also taken a ARC-AAA through with no questions asked. I can't tell you anything else except:
I expect problems and try to avoid them. Most of the items that might be "questionable" (larger lights, knives) were in my checked baggage and I invited them to open by accepting the conditions...no problems.
That said what I travel with..even in my checked baggage, could not, by intelligent people, I hope, be considered of intsruments of aggressive intent.
Caveat:
This appies to only the airports I have been through recently:
Las Vegas, Balitmore, Hartford, Denver, Omaha, Salt Lake, Chicago and a few others.
Most airport authorities employ their own security personnel and they screen you first or at the same time and places can be different in their interpretation of the regulations.
