No can do, chief - the cops screen out applicants whose IQs are too high.
So, cheat on the test and show everyone how it is done.
By the way, there is no national standard for testing. So, find a department, test and become one, raise their IQ, do the job well, serve as an example.
Let me know how it goes.
I think the IQ limit is more about racial quotas rather than job turnover.
