KMOV St. Louis has been running a lot of spots about the Wentzville offices of Serco that were given a $1.2 billion contract to process ACA, or Obamacare, applications. If you have been following the news story, you know that they basically paid employees to do nothing, and processed almost no applications.
They were just given a big fat $98 million government extension.
They run immigration Detention Facilities in the UK. Give driver's licence and driver exams in Ontario.
Serco haven't just overbilled the US. Check out their contracts and follow the pattern of scandal. In the UK they billed the Ministry of justice for (electronically) tagging offenders THAT WERE DEAD.
Oh, and their hospital management?
From the Wikipedia link:
In health services, Serco's difficulties include the poor handling of pathology labs and fatal errors in patient records. At St Thomas' Hospital, the increase in the number of clinical incidents arising from Serco non-clinical management has resulted in patients receiving incorrect and infected blood, as well as patients suffering kidney damage due to Serco providing incorrect data used for medical calculations. A Serco employee later revealed that the company had falsified 252 reports to the National Health Service regarding Serco health services in Cornwall.
And isn't it nice to know that all of that personal medical information is in the hands of one of the largest intelligence contractors in the world?
Yes, they are rapists, too:
(Also from the Wikipedia article)
In September 2013, Serco was accused of extensive sexual abuse cover-ups of immigrants at Yarl's Wood Immigration Removal Centre prison in Bedfordshire, England 
The Union of Christmas Island Workers highlighted the systemic failure by Serco to manage the Christmas Island Immigration Reception and Processing Centre. The centre detains a large number of refugees including 1,000 children. Under Serco, there has been an increase of deaths in custody, self-harm, and of Serco staff beating prisoners. As well, there has been a deterioration of facilities leading to the decline of the physical and the mental health of detainees and of staff. Ombudsman Allan Asher on the Australian radio show AM said, "In the first week of June when I visited Christmas Island, more than 30 incidents of self-harm by detainees held there were reported." Serco, in a staged memo leaked to The Australian, blamed the detainees for "creating a culture of self-harm," in order to use it as a "bargaining tool."
How did they do with that School district?
Serco held a 10-year contract with Bradford City Council between 2001 and 2011 to manage and operate the local education authority, providing education support services to the City's schools. This period was marked with "real problems" according to senior council officials and was taken back in house by the local authority after this period. Serco similarly manages and operates Walsall and Stoke-on-Trent local education authorities. Serco is one of Ofsted's three Regional Inspection Service Providers, responsible for school inspections in the English Midlands. Serco is also the provider of a Student information system, Facility, used in schools and colleges in several countries.[70
What DOESN'T Serco have it's fingers in?
EDIT: Consider the fascist possibilities of a corporation that control's driver licencing, education, prisons, medical care, detention, as well as intelligence gathering, cyber-spying, etc, globally. If we made a map that showed the influence of Serco and their other corporate peers (CACI, Lockheed, etc), would we see a world dominated by U.S./British private intelligence corporations?
Also, consider that Serco does the same work as USIS, LLC, the company that put Snowden at the NSA,
In fact, here is Serco's protest of a contract award to USIS, LLC:
Happy Fourth of July!
SI International's 2008 purchase date is not coincidental to the global financial collapse. It is too big to go into in this post, or in a blog post at all, it is book length, but SI ties to the Bush family and W's presidency, and probably back to WW2 and St. Louis investment banker Herbert Walker (GW Bush maternal grandfather, and founder of the bank that GW Bush's brother William "Bucky" still runs. And let's not forget the banker that laundered gold for the Nazi's, Thomas McKittrick, from St. Louis. After WW2 he brought Reichbank's Emil Puhl to NYC.)
It is worth reading the whole list. Guess who else?
USIS= (listed as a consortium sub-contractor under the Boeing project listing)= the contractor that vetted Edward Snowden, however, mostly famous for their ties to the Bush regime's Carlyle Group, who are famous for their Iraqi war profits, and sub-prime mortgage crisis insolvency.
SECOND EDIT: Not big on 9/11 conspiracy theories, but Serco comes up in doc's a lot on such sites. Their CEO (he retired just last year) was on the 47th floor of one of the towers on 9/11
