Along with Mr. Ziglar, Mr. Anderson, an immigration specialist and former top Senate Republican aide, is one of the few political appointees at the agency.I think this answers your question about why no one got fired, they are protected by Civil Service rules.
Can't be just let go without a drawout process!
--I think this nation needs an entire makeover, not just the INS. First would be a total ban on 'career' employment. I'm serious. Term limits in a way. I would say ten years total cumulative is plenty "government service", then no pension, last check, good bye, back to private sector. there's zero incentive to do anything productive in government by the employees. Zero. Nada. So it don't happen, it just gets worse and worse.
That would probably do more than the 2-4-6 years reshuffling of the politicians. Put them on 10 years cumulative max, too, same as any other employee.
