The GAO just a released a “report”:http://www.gao.gov/new.items/d0943.pdf with some hot PSI action. Essentially, it says that the administration has failed to implement past GAO recommendations regarding the initiative.
Based on a quick glance of the report, I think these two sentences sum up the critique pretty well:
bq. [N]one of the agencies [DoS,DoD, law enforcement agencies] has established performance indicators to measure the results of PSI activities. Consistent with internal controls, establishing clear PSI policies and procedures and indicators to measure results will help the agencies better organize their PSI activities.
