1. He (Sen Webb) apparently did little to extricate a fellow marine from jail for an error which most likely was caused by himself (Webb).
2. He hemmmed and hawed at the press conference, avoiding taking responsibility for ownership and possession of the weapon while in DC. My take is Sen. Webb is showing he is more worried about criminal charges resulting from his own behavior than the fact that his own assistant was arrested for possesion of the senator's weapon.
I think it is low character to allow a subordinate to sit in jail for something you did wrong.
This might make the Capitol Police rethink their policy of letting elected members to bypass the security screening. Webb might have been carrying in DC since he arrived there in January.
That's how I see it. My guess is that the entire staff is probably having second thoughts about working for him. Wonder what morale looks like in there now?
