Personally, I don't have a problem with flight crew bringing whatever they want through security. First, if the pilots intend evil, I doubt they'd need any "accessories", since they're in control of the aircraft. As for the FAs - if they intend evil, it doesn't take much creativity to figure out what might be helpful from the galley and/or service carts.

The real problem is that all the "security measures" are nothing more than a "floor show", put on at taxpayer expense, to "impress" the travelling public.
