The TSO at the TDC was not doing that to be a jerk. It is now policy at several airports, possibly to expand to many/all airports. But I guess many here will see a TSO carrying out a policy they do not like as that TSO being a jerk. Like the guy last year who filed a complaint about me because I was "rude" for using the HHMD on him when he alarmed the WTMD.

Actually, the TSO encounted by the OP at the TDC was doing what all of you have been screaming for - following TSA policy, not making up their own rules, and being consistent. You may not like the policy, but that is a different world than this TSO being a "jerk".
